I just try a table with <ol> as list elements with which it is possible to insert new table row.
<table>
<thead>
<tr>
<th>head</th>
<th>head</th>
<th>head</th>
<th>head</th>
</tr>
</thead>
<tbody>
<ol id="list">
<li><tr><td>row</td><td>row</td><td>row</td></tr></li>
</ol>
</tbody>
However, I have the problem that the element appear outside of my tables. When I add dynamically content via .append(), the formatting is not taken some elements gets removed.
Jsfiddle example
I want to use this solution for counting currently positions in an "container list".
I got a similar function like the example below for counting my lists, that's working great but the insert into the table does not work properly.
countinglists example: Nested ordered lists
Maybe its possible to achieve that counting syntax in a table without the <ol>? or is there any <ol> equivalent?
You need to do some reading on basic HTML: http://www.w3schools.com/html/html_tables.asp
Here is how it should look...
<table>
<thead>
<tr>
<th>head</th>
<th>head</th>
<th>head</th>
<th>head</th>
</tr>
</thead>
<tbody id="list">
<tr>
<td>row</td><td>row</td><td>row</td><td>row</td>
</tr>
<tr>
<td>row</td><td>row</td><td>row</td><td>row</td>
</tr>
<tr>
<td>row</td><td>row</td><td>row</td><td>row</td>
</tr>
</tbody>
In theory, you should be able to use CSS counters.
table {
counter-reset: myTableCounter;
}
thead th:first-child:before {
display: table-cell;
content: "";
}
tbody td:first-child:before {
display: table-cell;
counter-increment: myTableCounter;
content: counter(myTableCounter);
}
However, when I attempted to do that I found there were issues with display: table-cell generated content.
You may have to look at adding additional elements to the table to generate the content inside the first cell of each row.
My question is: what are you trying to achieve? Is this an exercise just to see how much can you stretch the HTML?
For your jsfiddle, the action associated to the click removes some of the HTML tags (at least on my browser) resulting in a <li>rowrowrow</li>, so you end up having a rather odd formatted-table. My renderer takes all <li> tags added by clicking as the content of a row; if you have only <li> tags, the dom parser will likely wrap them into a <ul> (it does on mine).
IMHO you don't need to use the ol to be able to count stuff. You can do it in jquery afaik. If you insist to use lists, then you probably need to style them and use e.g. divs inside (styled too). Emulating a table via a list and divs is madness imho :)
Update - for the hierarchical table
My idea would be to have something similar to this jsfiddle. I basically styled in the .sub and the .main classes. However, things get a bit more complex is you need to add some extra columns. In this case, you'd need something like a treetable.

With plain JavaScript, how can I get all the elements who do not have a CSS style? I need to get the rows of a table which are not hidden, and they don't have an explicit 'display' attached.
<table>
<tr class='form-row-links'>
Stuff...
</tr>
</table>
document.querySelectorAll('.form-row-links[style="display:is_not_none;"]') //pseudocode, of course :)
The css style display=none is applied after the initialisation of the page, to the <tr> element.
Thanks to #Ry- for pointing me towards the getComputedStyle
I actually thought that I could just declare an initial style of the row, which might then be overwritten by my JavaScript with 'none' or not:
<table>
<tr class='form-row-links' style='display:table-row;'>
Stuff...
</tr>
</table>
document.querySelectorAll('.form-row-links[style="display:table-row;"]')
Initially, I can't change the class name for instance:
<table class="firsttable"> This is the firstable that must be left align
<tbody>
<tr>
<td>
<table class="firsttable"> And this is the second table that must be center align
<tbody>
<tr>
<td>
How do I code it in css?
You can use below CSS, It works as intended
<style>
.firsttable:nth-child(1) { text-align:left; }
.firsttable:nth-child(2) { text-align:right; }
</style>
It's CSS3 though.
First table CSS selector:
.firsttable:first-of-type
If second table is last:
.firsttable:last-of-type
Otherwise, second table CSS selector is this:
.firsttable:nth-of-type(2)
Use ids:
HTML:
<table class="firsttable" id="table1">
...
</table>
<table class="firsttable" id="table2">
...
CSS:
#table1 {
text-align:left;
}
#table2 {
text-align:right;
}
Does this work?
In this case it is better or from my sense I always make it by adding an inline style in the table and I think their no need to create any other style for it in CSS.
<table class="firsttable" style="text-align:left"> This is the firstable that must be left align
And the second table may be another inline style of text-align:center
<table class="firsttable" style="text-align:center"> And this is the second table that must be center align
It is the best approach. But you can also can create some different id here or
.firsttable:nth-child(1) { text-align:left; }
.firsttable:nth-child(2) { text-align:center; }
Problem in this is if you use it then if another table appear in this web page area than it will arise a problem. So it is better to use inline style in this case.
If you want to move the table to the left and one to the right add the following to the appropreate table.
For the align right. Add this at the opening tag <table>.
style="float:right;"
For the algin left add the same code to the exactly same place but change the "left" to "right" depending on where you want it to be.
To aling text do as the other people have seggested.

I am trying to hide subsequent tr's with role="metadata" and the same data-group-id as the first occurring tr.
I cannot use JavaScript here and I am trying to achieve this using pure CSS.
<table>
<tbody>
<!-- BEGIN this tr should be visible -->
<tr data-group-id="1" role="metadata">
<td>
First rows group title
</td>
</tr>
<!-- END this tr should be visible -->
<tr data-group-id="1" role="data">
<td>
Row belonging to group 1
</td>
</tr>
<!-- BEGIN this tr should be hidden -->
<tr data-group-id="1" role="metadata">
<td>
Rows group title
</td>
</tr>
<!-- END this tr should be hidden -->
<tr data-group-id="1" role="data">
<td>
Another row belonging to group 1
</td>
</tr>
<!-- BEGIN this tr should be visible -->
<tr data-group-id="2" role="metadata">
<td>
Second rows group title
</td>
</tr>
<!-- END this tr should be visible -->
<tr data-group-id="2" role="data">
<td>
Row belonging to group 2
</td>
</tr>
</tbody>
</table>
Selectors like this...
[data-group-id="1"][role~="metadata"] ~ [data-group-id="1"][role~="metadata"]
display: none
... work very well, except that data-group-id may change dynamically.
Something like this would be perfect (I know that this is invalid CSS code, its just my fantasy with regular expressions to help illustrating the problem):
[data-group-id="(.*?)"][role~="metadata"] ~ [data-group-id="\\1"][role~="metadata"]
Is there any way I can achieve this using only CSS?
Thanks in advance.
Seems to me that using the data-group-id in CSS is impractical, especially since it's dynamically mutable and conditions of wether an element is hidden or not change. You end up with a huge chunk of CSS thats impossible to maintain.
In the initial rendering, it might be better to add a className so you determine serverside wether the initial state should be shown or not.
<tr data-group-id="1" role="data" class="hidden">
<td>Another row belonging to group 1</td>
</tr>
I am assuming JavaScript is used to dynamically change data-group-id, so why not use JavaScript to add/remove the className "hidden" when/where it makes sense. At least in JavaScript you CAN use regular expressions ;)
When you get to the point where you have to write impossible, long winded, error prone and unmaintainable CSS expressions, you're doing something wrong.
You're going to have to write some code to achieve this anyways, might as well do it the clean way instead of trying to shoehorn it into a styling language that isn't fit for the job.
I'm great with CSS but I largely suck at jQuery. We all have our limitations...
OK with that admission out of the way I'll begin. We have a "favourite products" table, which you can sectionalize into categories (eg, Booze, Sheep, Spoons). Each category is a . Each row (excluding the ) is a product.
I want to enable a user to drag and drop (reorder) the table rows, even between tbodies. I've looked at Table Drag and Drop (DnD) plugin for jQuery but was disappointed to find that it doesn't really support dragging between tbodies - and hasn't been updated for quite some time.
Here is the basic table structure:
<table>
<thead>
<tr>
<th>Favourite</th>
</tr>
</thead>
<tbody>
<tr>
<th>Spoons</th> <!-- secion title, not draggable -->
</tr>
<tr>
<td>Wooden Spoon</td>
</tr>
<tr>
<td>Metal Spoon</td>
</tr>
<tr>
<td>Plastic Spoon</td>
</tr>
</tbody>
<tbody>
<tr>
<th>Nuclear Bombs</th> <!-- seciont title, not draggable -->
</tr>
<tr>
<td>US Nukes</td>
</tr>
<tr>
<td>Soviet Nukes</td>
</tr>
</tbody>
</table>
I'm going to need to turn of the "dragability" of certain rows such as the first row in the - this being the section title.
Is there a better version of a jquery plugin out there that can do what I need? If you can find a better plugin please share and win my "favourite person of the week" award.
Thank you.
Your going to want to use jQueryUi's sortable plugin and then use the option
connectWith: '.connectedSortable'
to connect the different table bodies.
the plugin is designed for lists, but it does work on tables, mostly. I've used it with success on a table before.
here's the link to the documentation on jquery ui's sortable:
http://jqueryui.com/demos/sortable/#connect-lists
EDIT:
you'll also want to use the items option to specify that certain rows are sortable
items: 'tr:not(.dontIncludeMe)'
Have you looked into jQuery UI's droppable widget? I'm wondering (since I haven't played around with your specific problem yet) if you could set your tbody as droppable and your tr as draggable. Or possibly add some classes to each to be able to specify that certain rows (non-title rows) are draggable...
UPDATE: more research turned up this SO question, which links to this other article about dragging table rows.
you can turn off the dragability in case od table dnd plugin by specifying
<tr class ="nodrag nodrop">
<th>Favourite</th>
</tr>
class nodrag nodrop will not allow drag and drop
and
class nodrag will not allow it to be dragged i hope it helped.
Having an HTML page with a simple table and js code to do show / hide on it:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>title</title>
<script type="text/javascript">
function showErrorSteps()
{
var el = document.getElementById("t1");
if(el.style.display=="none")
{
el.style.display="block";
}
else
{
el.style.display="none";
}
}
</script>
</head>
<body>
<br />
<span onclick="showErrorSteps()">[click]</span>
<br />
<br />
<table id="t1" border="1" width="100%" style="table-layout: fixed">
<tr>
<td>s</td>
<td>d</td>
<td>a</td>
</tr>
</table>
</body>
</html>
What happens is that on Mozilla the table gets resized after you click twice(even with the table-layout: fixed css). IE works fine.
Tables shouldn't be set to display: block. Table rows and cells shouldn't either. They have different display values. My advice? Don't do it this way. Use a class:
.hidden {
display: none;
}
and dynamically add it and remove it from the table to avoid problems of setting the right display type on an element that you show.
Edit: To clarify the comment as to why do it this way and what's going on. Try this:
<table>
<tr>
<td>Cell 1</td>
<td style="display: block;">Cell 2</td>
</tr>
</table
It will (or should) screw up your table layout. Why because a <td> element, by default, has display: table-cell not block. Tables are the same. They have display: table.
Unsetting CSS attributes is... problematic.
Thus you are best off using classes to set and unset attributes. It's easier to change (the class resides in a CSS file and isn't code), avoids problems like setting the value back to the correct original value and generally provides a cleaner solution, especially when used with a library like jQuery. In jQuery, you can do:
$("table").toggleClass("hidden");
Done.
Or you can use addClass() and removeClass() if that's more appropriate. For example:
<input type="button" id="hide" value="Hide Table">
...
<table id="mytable">
...
and
$(function() {
$("#hide").click(function() {
if ($("#mytable").is(".hidden")) {
$("#hide").val("Hide Table");
$("#mytable").removeClass("hidden");
} else {
$("#hide").val("Show Table");
$("#mytable").addClass("hidden");
}
});
});
And there you have a robust, succinct and easy-to-understand solution (once you get your head around the jQuery syntax, which doesn't take that long).
Messing about with Javascript directly is so 2002. :-)
This is not a direct answer to your question, but a serious recommendation. I have recently discovered the joys of JQuery. All this kind of stuff can be done effortlessly and there is extensive online examples and references available.
If you haven’t got time to get into it now then I’m sure someone will offer a solution here, but I would recommend anyone who does anything beyond the most cursory JavaScript DOM manipulation to consider JQuery (or a similar framework).
JQuery offers browser independent Hide(), Show() and Toggle() methods. Here’s one of my favourite references.
This might be because you set the style.display to "block". Try to set it to "". You should also set the table width using CSS. (width: 100%;)
