Build a custom table with more than one header row, with the possibility of grouping the header cells, by merging cells. The header rows are built in a easy way using the "normal" table widget and then a JS script adds those rows on top of your records table, where the data is populated. This is ideal for complex spreedsheet like reports, with multiple rows in the table header, and it allows to keep using the outsystems list sort and navigation (pagination) widgets. The table header can be designed with the possibility to add multiple rows and merging header cells horizontally or vertically.
