I'm trying to implement irregular headers on my table records. Something like this https://www.w3.org/WAI/tutorials/tables/irregular/

I saw that we have a option to merge cells and insert rows, but this last options is disable. It is possible to use this function?

Hi David,

You can add a row before the table, having the structure you want for the header by using a table (design column and rows containing the text you need).
