:-) Once I found myself in the same situation, there was no jQuery plugin matching my requeriments, so I spend some time developing my own one: colResizable
colResizable is a free jQuery plugin to resize table columns dragging them manually. It is compatible with both mouse and touch devices and has some nice features such as layout persistence after page refresh or postback. It works with both percentage and pixel-based table layouts.
It is tiny in size (colResizable 1.0 is only 2kb) and it is fully compatible with all major browsers (IE7+, Firefox, Chrome and Opera).
colResizable was developed since no other similar plugin with the below listed features was found:
colResizable is the most polished plugin to resize table columns out there. It has plenty of customization possibilities and it is also compatible with touch devices. But probably the most interesting feature which is making colResizable the greatest choice is that it is compatible with both pixel-based and fluid percentage table layouts. But, what does it mean?
If the width of a table is set to, lets say 90%, and the column widths are modified using colResizable, when the browser is resized columns widths are resized proportionally. While other plugins does behave odd, colResizable does its job just as expected.
colResizable is also compatible with table max-width attribute: if the sum of all columns exceed the table's max-width, they are automatically fixed and updated.
Another great advantage compared with other plugins is that it is compatible with page refresh, postbacks and even partial postbacks if the table is located inside of an updatePanel. It is compatible with all major browsers (IE7+, Firefox, Chrome and Opera), while other plugins fail with old IE versions.
See samples and JSFiddle.
$("#sample").colResizable({
liveDrag:true
});
So I started writing my own, just bare bones functionality for now, will be working on it next week... http://jsfiddle.net/ydTCZ/
Here's a short complete html example. See demo http://jsfiddle.net/CU585/
<!DOCTYPE html><html><head><title>resizable columns</title>

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

$( "th" ).resizable();

try flexigrid, here is One more Reference
Or try my solution: http://robau.wordpress.com/2011/08/16/unobtrusive-table-column-resize-with-jquery-as-plugin/ :)
Although very late, hope it still helps someone:
Many of comments here and in other posts are concerned about setting initial size.
I used jqueryUi.Resizable. Initial widths shall be defined within each "< td >" tag at first line (< TR >). This is unlike what colResizable recommends; colResizable prohibits defining widths at first line, there I had to define widths in "< col>" tag which wasn't consikstent with jqueryresizable.
the following snippet is very neat and easier to read than usual samples:
$("#Content td").resizable({
handles: "e, s",
resize: function (event, ui) {
var sizerID = "#" + $(event.target).attr("id");
$(sizerID).width(ui.size.width);
}
});
Content is id of my table. Handles (e, s) define in which directions the plugin can change the size. You must have a link to css of jquery-ui, otherwise it won't work.
I tried to add to @user686605's work:
1) changed the cursor to col-resize at the th border
2) fixed the highlight text issue when resizing
I partially succeeded at both. Maybe someone who is better at CSS can help move this forward?
