DataTable does not assign colspan correctly when working with filters

[atach]

When using "Row Groups" and "Filters" in components "DataTable", the component computes and assigns the colspan for "template #empty".

And it turns out that the table template looks different. But when nothing is found in the table, the table looks different because there is no column by which to group. How to be?
