I want to create a rather large table consisting of several topics/categories each with a number of sub-items. I am able to create the table and add custom filters, etc.
However, since filtering and sorting expects the headings to be in the first row, I was not able to add a different first row with merged cells and a category headline. This makes the table rather difficult to work with.
Is there a possibility to add a first row with the categories and shift the filtering and sorting options to the second row?
