Hey,
When using the filter extension(latest for 15/2/16) and having columns with rowspan/colspan which one
of them is hidden the filter breaks the table.
Here is an example:
http://jsfiddle.net/3L4ej4dx/242/The example shows a table which has a column with colspan:2 that one of them is hidden.
Everything works fine until the filter is enabled(by pressing the enable filter button).
Thanks.
