I need to implement a table, in which I can both resize columns and scroll trough the body (as seen here). I am currently using colResizable to resize columns, but I was unable to find a way to make the body scrollable and still keep the columns resizable. colResizable only changes the header's width and expects the columns to behave the same way.
As far as my research went, it is only possible to do scroll through the body by setting display: block on <tbody> which will ultimatly screw up colResizable.
Changing the width of the columns on each drag via JavaScript is possible, but I'd rather go for a html + css only solution, since the table will contain multiple hundred if not thousands of rows and it might effect the performance.
If one of you guys knows a way around this, please let me know.
Edit 1: Unfortunately I am not able to post any code related to my project, since it may contain confidential information, but I believe it is not needed anyways since this problem is not specific to my existing code.
Edit 2: I forgot to mention, that I am using <thead> for my headers. As C4pt4inC4nn4bis pointed out, it is easily doable to resize columns and scroll through <tbody> when not using a <thead> tag. Since I want my headers to stay on top of the table, even while scrolling, I can't simply move everything in <thead> to <tbody>.
It's impossible to show Y-axis scroll at without display:block option.
Also colResizable doesn't support this situation.
Without , the headers can't not be fixed on the top.
Check this code. I manually resize columns whenever resize the table head.
There is an event handler (onDrag) in the colResizable plugin.
$("table").colResizable({
liveDrag: true,
onDrag: function (e) {
$("tbody tr td:nth-child(1)").width($("thead th:nth-child(1)").width());
$("tbody tr td:nth-child(2)").width($("thead th:nth-child(2)").width());
$("tbody tr td:nth-child(3)").width($("thead th:nth-child(3)").width());
$("tbody tr td:nth-child(4)").width($("thead th:nth-child(4)").width());
},
});
If you do not use the liveDrag option, use the onResize event handler.
Hope it helps.
Thank you.
I found when I use various explorer to test $(xxx).width() in the td of table will be going to lead me to the different width,so could anyone give me a perfect solution to get the same width or same with chrome.VRPMain is the telerik grid.
$("#VRPMain>table>tbody>tr:first-child>td").each(function (i, item) {
tempArr.push(Math.floor($(item).width()));
});
I am working the (fantastic) jQuery DataTables plugin and have begun to use the 'Responsive' extension so that it responds well on varied devices etc.
It is working fine however it adds some buttons to allow each row to be expanded to show the columns which have been hidden.
However, this is actually really annoying since it shows all the columns I have deliberately not shown as well as not looking ideal (imho).
Does anybody know how to remove these buttons?
Cheers,
Jack
I did a bit more or an intensive search of the docs and found that these 'expanded rows' are refered to as child rows and can be disabled as follows.
Initially I simply included the
"responsive": true,
tag in my datatables. These child rows may be disabled with:
"responsive": {
"details": false
},
I thing you can override the CSS style of this button and hide it from user:
table.dataTable.dtr-inline.collapsed>tbody>tr>td:first-child:before,
table.dataTable.dtr-inline.collapsed>tbody>tr>th:first-child:before {
display:none
}
Change also the padding of the cell:
table.dataTable.dtr-inline.collapsed>tbody>tr>td:first-child,
table.dataTable.dtr-inline.collapsed>tbody>tr>th:first-child {
padding-left: 10px; /* Instead of 30px */
}
I had been developing a screen which has lots of data as . It is scrolling with dataTable.(Horizontal Scroll). There is a drpdown which should filter values and should show only eligible TDs in scroll part. Below are Screenshots. I am hiding and showing data based on selection of a dropdown.
Have added a class to all tds and rowspan th so that they can be toggled based on selction of dropdown.
It Shows perfect while fetching all the records. But when I hide columns , columns work perfect but header resizes its headings.
Here is what happens on hiding th and td .td remains same , th resizes
I tried a lot but cud not fix it. Can someone plz help
So I got the solution .
U need to get your table object again and redraw it. After reading so many places about this error it seemed dataTable is still to find a fix for hiding columns in scroll part with rowspan added to it.
What I did was adding a class to all th, td of table which needs to be hidden based on any condition , here based on selection. When I was selecting a partical type I added another class to hide the required th and tds. But Th reset sizes ,might be because of scrolls added.
It resets width of entire header leaving your td as it was . So it looks ugly.
oTable.fnDraw();
Just take reference of your table and draw again.
I have a html table and I want to freeze the header row th tag for scrolling the data. How I can do that? Does I need to use the Dom?
Thanks !!
My solution is to use two tables and fix the column widths. The lower table is in a scrollable div and has no header.
If you take Accessibility seriously, two tables is not the way to go since it breaks rules.
There are ways to do it in pure CSS, but it is a headache to get it to work in all browsers. There are a few examples out on the net, but they do not all work 100% with IE without tweaks.
I am currently working on a CSS only version, this is getting pretty close: http://www.coderanch.com/t/431995/HTML-JavaScript/Table-with-fixed-header-scolling#1918825
Does not work in IE8rc1 yet, IE6/7 has a border issue and you have to live with the scrollbar looking different in FF vs IE.
With FireFox, you can put style="height: 200px; overflow-y: auto" But to have a pure CSS version compatible with all major browsers, I've use this example since IE doesn't support syles in tbody or thead.
I have come up with a solution that sort of combines two previously mentioned ones. It uses jQuery and two tables , one for the header and one for the content. The header table is set to a width of 100% with no column widths set. At the bottom of the content table there is a row defined to match the header table with the column widths set. This row is hidden so that it is not shown, but retains the column widths.
For this example I gave my header row an ID of 'Header1' and the bottom row and ID of 'Header2'. Also I wrapped the content table inside a div with an ID of 'scrollTable'.
I set styles in my CSS file for the scrollTable ID, see below:
#scrollTable {
height:250px;
overflow-x:hidden;
overflow-y:scroll;
}
Now for the jQuery part. Basically what I'm doing here is taking the widths of the bottom row columns and setting the header columns to match. I stretch the width of the last column of the header so that it fits over the top of the scroll bar. See code below:
$(document).ready(function(){
var maxWidth = $('#Header1').width(); // Get max row Width
$('#Header2 th').each(function(i) { // Set col headers widths to to match col widths
var width = $(this).width();
$('#Header1 th').eq(i).width(width);
});
var blankSpace = maxWidth - $('#Header1').width(); // Calculate extra space
$('#Header1 th:last').width( $('#Header1 th:last').width() + blankSpace ); // Stretch last header column to fill remaining space
});
I have tested this successfully on IE 6, 7 & 8, Firefox 3.0.1.4, Chrome 3.0.195.25, Opera 10, and Safari 3.2.2 on Windows XP.
I've done it in the past using CSS by defining a height for the <TBODY> tag on my table, and using overflow:auto. This was a while ago, and I think there were some compatability problems. I don't remember precisely what they were, but this solution may work for your problem.
the best solution (the one that scales with lots of data) is to use 2 tables like aaron said, the top table has the headers, and the bottom table should have the headers as the last row (or the footer), but with opacity of 0, so that you cannot see them.
This the headers at the bottom make the bottom table have the same column widths as the top table, making things line up. make sure you style both header and footer the same.
you will also have to create a seperate scroll bar for vertical scrolling to the right of the table, because otherwise the scroll bar will mess up your widths. add a scroll event listener to set the scrolltop of the table to the scrolltop of the scrollbar, and resize the scroll bar to be the same height as the table.
its pretty easy, actually =)
Create a single table as you normally would to meet accessibility concerns. Dynamically create a new table based on the thead using jQuery (copy the thead) and inject it into the page above the first table and give it the fixed position. It should stay in place while the rest of the table scrolls, but it will still remain accessible and work with JavaScript disabled.
Have you tried this plugin from JQuery ? http://plugins.jquery.com/project/floatobject
I believe this does what you want. Check out the demo # http://amirharel.com/labs/fo/float_demo.html
