I would like to distribute the columns on a percentage basis on the grid. Is there any way to do that?
I managed to do that using CSS. However, this no longer works as soon as "grouping" is used. A "colgroup" element is inserted, whose "col" elements also need a width. Is it possible to give these "col" elements a style somehow?
I have created a small example of this. It looks good at first sight. As soon as I arrange the columns differently or use a second grouping level, the distribution is no longer correct.
