Stop site.css overriding table style - javascript

In my ASP.NET's MVC application, table style in site.css file is defined as:
table {
border-collapse: collapse;
border-spacing: 0;
margin-top: 1em;
border: 0 none;
}
When I'm creating a table and setting explicitly the border property in my HTML, this style in css is overriding the border property. Result is I'm not able to see borders in my table. This is my table variable:
tableT = '<table border="1" style="float:center" id="itemList"><thead><tr><td></td><td>Total</td><td>Completed</td><td>Inprogress</td><td>Pending</td></tr></thead><tbody></tbody></table>',
I want a table with borders, I don't want to change site.css as everywhere else that is being used.

You could try using an inline style with an !important rule:
<table border="1" style="float:center; border: 1px solid !important;" id="itemList">
However, this is quite a messy hack, and Germain's answer from the comments would be a more elegant solution - it depends if you are able/inclined to edit your CSS file.

ember-drag-sort: implementing a sortable list based on an HTML table?

Originally asked by #livfwd on GitHub.
It seems like the :before :after pseudo-elements break the table layout and put the placeholder in unexpected places when dragging rows within a table.
Are there any known workarounds for this?
ember-drag-sort uses a simple CSS technique to render the placeholder: :before and :after pseudoelements.
Unfortunately, this doesn't work with HTML tables because table semantics are very restrictive. To work around this problem, top/bottom padding on table cells can be used instead of selectors.
This is not a great solution because padding appears inside table cells. If you want your cells to have borders, you'll have to apply them to inner elements instead.
Tables are now part of the demo, please have a look.
Here are the CSS overrides used in the demo:
table {
width: 100%;
}
table.dragSortList.-isExpanded {
padding: 15px;
background-color: #f6f6f6;
}
table.dragSortList.-isExpanded.-isDraggingOver {
background-color: #eee;
}
table.dragSortList.-isExpanded.-isDraggingOver:before {
content: none;
}
tr.dragSortItem.-placeholderAbove:before,
tr.dragSortItem.-placeholderBelow:before {
content: none;
}
tr.dragSortItem.-placeholderAbove td {
padding-top: 25px;
}
tr.dragSortItem.-placeholderBelow td {
padding-bottom: 25px;
}
table .the-item {
margin: 0;
}
If this approach does not suit you, unfortunately, this addon currently cannot offer anything else. You'll have to either revert to divs or use another drag-sorting addon.

How to add column separators with angularjs ngTable

I'm using the "ngTable" component (enter link description here) in my AngularJS app to present tabular data. It's a little simpler to use than ngGrid, and I don't like how ngGrid configures your table (I especially don't like putting the table header strings in javascript, instead of in the HTML).
Although ngTable works well enough, there appear to be some limitations in its configurability. For instance, I'd like to just add column separators to the header and cells. The way ngTable is referenced in HTML, you don't specify the table header elements, just the cells. I suppose I could put a class on the "td" elements to add separators to the cells, but that wouldn't affect the header.
Anyone got some ideas of how to do this?
You can just do that in CSS
table.ng-table thead th:not(:first-child) {
border-left: 1px solid red;
}
table.ng-table thead th:not(:last-child) {
border-right: 1px solid red;
}
table.ng-table tbody td:not(:first-child) {
border-left: 1px solid blue;
}
table.ng-table tbody td:not(:last-child) {
border-right: 1px solid blue;
}
Example here: http://plnkr.co/edit/t77lzM1o6Xh2PBnhZqw6?p=preview
The only downside to this approach is that it won't work in IE <9.
To get it to work on IE <9 then you would have to add classes to each column when you define the <td> and match them in css.
If you only want a border for a specific column then the css is actually easier as you can just add a class to the column you want the border on and then in your css just add a border-left or border-right for that td.col-style-name

IE8 doesn't apply css display dynamically

I'm trying to develop a table that hides its columns upon a given value. I am using a solution discussed in another SO question. As part of the suggestion there they say that to support IE<8 browsers a hide rule should be used instead and show by default. (My browser is in quirks mode).
I have several hide rules that look like the following.
table.Show1 .cellType2, table.Show1 .cellType3{
display:none;
}
So what I expect is cellType2 and cellType3 to hide when the className of the table is changed dynamically. With the initial values it works fine but when the className of the table changes dynamically, it hides the cells needed but it doesn't bring the other back.
I went through it with IE Developer Tool and I know that the className of the table is set properly. I also inspected the cell element's style and there is no display rule set so I would expect to display as default, but it isn't(it doesn't show up).
What I found most annoying it that if I change ANY style property in the Developer Tool, it will realize that it should be displaying the cell and then , it brings it back up.
Why the style is not applied? Please help me fix this issue.
EDIT:
I'm including a "minimal" code to recreate the issue.
JavaScript:
function typeChanged(name, id)
{
var elem = document.getElementById(id);
elem.className = name;
}
CSS:
table td
{
border-top: 1px none #000066;
border-right: 1px none #000066;
border-bottom: 1px solid #000066;
border-left: 1px solid #000066;
}
table.Show1 .cellType2, table.Show2 .cellType1{
display:none;
}
table.Show1 td,table.Show2 td
{
border-style: solid solid solid solid;
border-width: 1px;
}
table.Show1 th,table.Show2 th,table.Show1,table.Show2
{
background: transparent none repeat scroll 0% 0%;
color: #000066;
border-style: none none none none;
table-layout: fixed;
}
HTML:
<select onChange="typeChanged(this.options[this.selectedIndex].value,'mytable')">
<option value="Show1">Show1</option>
<option value="Show2">Show2</option>
</select>
<table id="mytable" class="Show1">
<tr>
<th class="cellType1">type1</th>
<th class="cellType2">type2-a</th>
<th class="cellType2">type2-b</th>
</tr>
<tr>
<td class="cellType1"><input type="text"></input></td>
<td class="cellType2"><input type="text"></input></td>
<td class="cellType2"><input type="text"></input></td>
</tr>
</table>
It sounds like it's not repainting the table. There are several IE 7 & 8 repaint and reflow oddies out there...
You can try forcing the repaint in your javascript, maybe just by hiding and showing the table with something like
document.getElementById('myTable').style.display='none';
document.getElementById('myTable').style.display='table';
or forcing a reflow on the entire page with something like
document.body.className=document.body.className;
It appears that there is a problem when trying to repaint the cells. Just from the CSS rule doesn't work but if we apply the display directly in the JavaScript then the cells are drawn properly. Looping trough the cells and applying the style directly works, I just had to have a name convention to easily identify the class that a cell is supposed to be.
if(isEmpty(cell.className)|| cell.className == (selectedType+"_cell"))
{
cell.style.display = 'table-cell'; // might be different for other IE versions
}
else
{
cell.style.display = 'none';
}

applying css class dynamically to table td not working in firefox

I want to add css class to td which is created dynamically and this is portion of my code
var newTD = document.createElement("td");
td is created but border is not coming.
td is added into table properly when user clicks on plus button.css is not applied.
css class is
table.ms_grid td, table.ms_grid table td
{
padding: 3px 5px;
border: 1px #D3E4F5 solid;
cursor: pointer;
}
this code is part of my project
please suggest solution.
Most table cell borders won't display unless there's something within.
The old method was to add a inside however I believe there's a CSS property to always show borders. Will edit if I find it.
There it is, empty-cells, supported in everything (current) except IE7 and below

Making a Table Row clickable

I wonder what the best way to make an entire tr clickable would be?
The most common (and only?) solution seems to be using JavaScript, by using onclick="javascript:document.location.href('bla.htm');" (not to forget: Setting a proper cursor with onmouseover/onmouseout).
While that works, it is a pity that the target URL is not visible in the status bar of a browser, unlike normal links.
So I just wonder if there is any room for optimization? Is it possible to display the URL that will be navigated to in the status bar of the browser? Or is there even a non-JavaScript way to make a tr clickable?
If you don't want to use javascript, you can do what Chris Porter suggested by wrapping each td element's content in matching anchor tags. Then set the anchor tags to display: block and set the height and line-height to be the same as the td's height. You should then find that the td's touch seamlessly and the effect is that the whole row is clickable. Watch out for padding on the td, which will cause gaps in the clickable area. Instead, apply padding to the anchor tags as it will form part of the clickable area if you do that.
I also like to set the row up to have a highlight effect by applying a different background color on tr:hover.
Example
For the latest Bootstrap (version 3.0.2), here's some quick CSS to show how this can be done:
table.row-clickable tbody tr td {
padding: 0;
}
table.row-clickable tbody tr td a {
display: block;
padding: 8px;
}
Here's a sample table to work with:
<table class="table table-hover row-clickable">
<tbody>
<tr>
<td>Column 1</td>
<td>Column 2</td>
<td>Column 3</td>
</tr>
</tbody>
</table>
Here's an example showing this in action.
With jQuery you can do something along these lines:
$('tr').click(function () {
$(this).toggleClass('highlight_row');
});
Then add a highlight_row to your CSS file and that row will change its class to highlight_row. You could swap out whatever you want to do in that line (as well as change $('tr') to fit your specific row.
I have found this solution which works quite well:
$(document).ready(function() {
$('#example tr').click(function() {
var href = $(this).find("a").attr("href");
if(href) {
window.location = href;
}
});
});
Just don't forget to style the cursor as a pointer on tr:hover
#table tr:hover {cursor: pointer;}
Source: http://www.electrictoolbox.com/jquey-make-entire-table-row-clickable/
"
The most common (and only?) solution seems to be using JavaScript, by using onclick="javascript:document.location.href('bla.htm');" (not to forget: Setting a proper cursor with onmouseover/onmouseout).
"
The onclick-command should look like this:
onclick="window.location.href='bla.html';"
And it isn't necessary to do anything onmouseover/-out about the cursor as a cursor-property only works when the mouse is hovering the element:
style="cursor:pointer;"
Another approach is to actually linkify the contents of each cell. You could change the style if necessary so they don't look like traditional links.
Note that what you are trying to do does break the intuitive user experience a little bit. It needs to be clear that clicking on a row does something. I usually prefer to put an icon at the edge of each row (a magnifying glass, etc.) which drills into a new page.
Fortunately or unfortunately, most modern browsers do not let you control the status bar anymore (it was possible and popular back in the day) because of fraudulent intentions.
Your better bet would be a title attribute or a javascript tooltip.
If your table does not have links inside, following trick should work.
Put entire table into a link and change the href attribute of the link in rows onmouseover events.
Demo code:
<script type="text/javascript">
function setLink(elRow) {
var elLink = document.getElementById('link');
elLink.href = elRow.rowIndex + ".com";
}
</script>
...
<a id=link>
<table>
<tr onMouseOver="setLink(this);"><td>first row</td></tr>
<tr onMouseOver="setLink(this);"><td>second row</td></tr>
</table>
</a>
I realise this is an old thread with a perfectly legit solution in Alice's answer. There is however also a way to do this without javascript AND without duplicating your link * the number of columns AND keeping your markup/CSS valid. It took me a while to figure out, so I thought I'd post it here for others that also happen to end up on this thread like I did.
Put the link in the first column:
<table class="search_results">
<tr>
<td>Some text</td>
<td>more text</td>
<td>more text</td>
</tr>
</table>
This is perfectly fine markup, so your only real issue is getting that link to span the width of your table. I did it like this using pretty standard CSS:
table.search_results a {position:absolute;display:block;width:98%;}
Change the width to whatever you want and in principle you are done and dusted. So that is all relatively easy, however if you, like me, have a fluid/responsive layout, and also some standard styling on your links plus some padding on your tables, you are going to need these rules (copied necessary from above and added extra).
table.search_results td:first-child {padding:0;}
table.search_results a {position:absolute;display:block;width:98%;max-width:1272px;font-weight:normal;color:#000;padding:.5em;}
table.search_results a:hover {background:none;}
table.search_results tr:hover {border-color:#25505b;background:#b5d6dd;}
To explain:
The first rule removes all padding on my first td ONLY. By default the padding on my td is .5em.
The second rule adds the same padding back on the link, otherwise you end up with misaligned cell contents. It also corrects a few standard styles I have on my a to ensure the columns all look the same. You could do this the other way around too (add the link styles to your td).
With the last two rules I get rid of the default hover effect on my links, then put it on the tr for any tables with the right class.
This works in the browsers I care about, but you should of course test in those you care about :) Hope I help save someone some minutes with this writeup!
It's a hack but you can add this to your tr:
onmouseover="window.status='http://bla.com/bla.htm'"
don't forget to style your fake links:
tr.clickable {
cursor: hand;
cursor: pointer;
}
You might also try wrapping the content of your row's cells in an href and using CSS to push the href height/width to the internal bounds of each cell. The row itself wouldn't be clickable (unless you added additional html to the row) but most of the content space of the row would act like a normal link (cursor, status bar, etc). I can't remember off hand exactly how I did this before but I was reasonably successful getting this to work.
Edit: A comment asked for more details and they were covered by a later post from another user but I didn't realize that until I looked further into this suggestion and tested it.
If you add "display: block" CSS style tag to the anchor objects in the cells that you want to be clickable it will make the entire cell (minus any padding) act like a button. The cursor is displayed correctly and it previews the link destination in the status bar. This is all done with zero javascript. Good luck.
I had that same problem, I solved it by using CSS only. I think it was the best solution for me, because I was using it in JSF also.
Just assign the style class to the table and you are good to go....
Here it goes:
CSS:
.myDataTable {
background: 444;
width: 100%;
}
.myDataTable thead tr {
background-image: url('../img/tableHeader.jpg');
}
.myDataTable thead tr th {
height: 28px;
font-size: 14px;
font-family: tahoma, helvetica, arial, sans-serif;
padding-left: 5px;
}
.myDataTable thead tr th img {
padding-right: 5px;
padding-top: 1px;
}
.myDataTable thead tr td {
height: 15px;
font-size: 11px;
font-weight: bold;
font-family: tahoma, helvetica, arial, sans-serif;
padding-left: 5px;
}
.myDataTable tbody {
background: #f2f5f9;
}
.myDataTable tbody tr:nth-child(even) td,tbody tr.even td {
background: #e2ebf4;
font-size: 12px;
padding-left: 5px;
height: 14px;
}
.myDataTable tbody tr:nth-child(odd) td,tbody tr.odd td {
background: #f7faff;
font-size: 12px;
padding-left: 5px;
height: 14px;
}
.myDataTable tbody tr:hover td {
background-color: #e7e7e7;
}
.myDataTable tbody tr td {
height: 14px;
padding-left: 5px;
font-size: 12px;
}
.myDataTable tbody tr td a {
color: black;
text-decoration: none;
font-size: 12px;
display: block;
}
.myDataTable thead tr th a {
color: black;
text-decoration: none;
font-size: 12px;
display: inline;
}
Your table structure should be:
<table class="myDataTable">
<thead>
<tr>
<th>Heading 1</th>
<th>Heading 2</th>
</tr>
</thead>
<tbody>
<tr>
<td>Data 1 </td>
<td>Data 2 </td>
</tr>
</tbody>
</table>
If your targeted browsers all support CSS Table display styles, you can use Javascript to wrap each row in an <a> tag styled to function as a <tbody>.
Here's some JS code using jQuery to make it happen: (jsfiddle)
$(function() {
$('.table-linked').each(function() {
var table, tbody;
table = this;
tbody = $('tbody', this);
tbody.children().each(function() {
var href, row;
row = $(this);
href = row.attr('data-href');
$('<a href="' + href + '" style="display: table-row-group" />').append(row).appendTo(table);
});
tbody.remove();
});
});
This code will transform a table that looks like this:
<table class="table-linked">
<tbody>
<tr data-href="/a"><td>a</td><td>1</td></tr>
<tr data-href="/b"><td>b</td><td>2</td></tr>
</tbody>
</table>
Into this DOM structure in the browser:
<table>
<a href="/a" style="display: table-row-group">
<tr><td>a</td><td>1</td></tr>
</a>
<a href="/b" style="display: table-row-group">
<tr><td>b</td><td>1</td></tr>
</a>
</table>
Browsers don't seem to be capable of parsing this structure as HTML code (and needless to say it won't validate), it needs to be constructed using JS
Marko Dugonjic, in his blog maratz.com, explained how you detect a table row index with Javascript. In his example, when you mouse over any cell in a row, the entire row is highlighted.
See example,
http://webdesign.maratz.com/lab/row_index/
and his article,
http://www.maratz.com/blog/archives/2005/05/18/detect-table-row-index-with-javascript/
With a change, you can adapt this further by placing an onclick action.
If you're already relying on javascript for the click, then you can also use javascript to show the url in status area, change the cursor, or do other things so it looks more like a link. Of course, the browser may ignore the code that sets the status area.
