When we add a number of options to the columns, we see the common variable as a group. This makes it much easier to understand the structure of the data in the table.
A similar feature was created for rows. You can now enable the display of groups on rows, if necessary. This is especially useful if we see repeating variables in rows (brands, for example), adding groups brings visual comfort and streamlines the data structure.
To switch on groups on rows, click on the 'three dots' icon in the left corner of the table and check up 'Show rows groups'. Uncheck it if you want to hide groups on rows.
