Hi, 

I think merging rows does not work with OutSystem DataGrid (not completely sure though). You can check this Cell merge

Hello @Kaori Ouchi,

Under some conditions, you can achieve that on some column types by using the client action MergeColumnCells described in the sample application.

Cheers,

Hello guys, one more question on this topic: 

Is it possible to merge cells in one column based on the reference of another column?

For example, in the table below, rows 2, 3, and 4 all belong to the same Version (RINF-RTST-V2-2025/9). In this case, I would like to merge only their Current Status cells.
Similarly, rows 5, 6, and 7 belong to a different Version (RINF-RTST-V1-2025/9), so I would like to merge their Current Status cells separately.
