The left table does not need tree mode. Can the first column be merged

Hello,

The left table does not need tree mode.

If you don’t want to have tree structure in the first column of the grid, you can remove tree parameter in the gantt.config.columns:

Please check the following snippet:

Can the first column be merged

If you want to merge several rows in one, unfortunately, there is no built-in way to do that in the grid of Gantt.
