The property you are looking for is "RowName"
If you want to change it programatically, and hTable is your table, you could do
hTable.RowName = 0:9;
In GUIDE, to do it interactively:
- Double Click on the table to bring up the Inspector
- Scroll down to RowName
- Click on "numbered" and choose "Show names entered below as the row headers"
- Then you can type in 0, 1, 2, ...
And try App Designer, it's not too difficult and well worth it to learn!
