Incorrect table header column widths when using rowGrouping with startRender

karishma10

Previously, I was using version 1.13.8 of the Datatable, and all the widths were working fine. However, as soon as I updated to any of the Datatable v2 versions, I started facing this issue.

Here is the test case:

Is there any way to fix this issue? Or is there any specific updated version where this issue is not present?

It is a problem with the colspan unfortunately. I've not yet got a workaround for this.

What appears to be happening is that in DataTables 2 the column widths are assigned using colgroup > col elements. This has proven to be much more reliable in every situation with the single exception of a colspan in the first row of a DataTable, such as in colgroup. The column widths from colgroup > col are being applied to the single cell of the grouping row, and it just doesn't work (unsurprisingly).

To my mind that is a bug in the browser table renderer, but it happens in all browsers.

What I think I'll need to do is, when using RowGroup, inject a hidden row into the table body as the first row and the widths can apply to that.
