Creating an index number for each row in a table is all done in the same table. It’s not something you set up across multiple tables. It’s just to give each row a sequential number and that’s it.
It’s not clear what you are trying to do, but I think your may be trying to do something using a solution meant for something else. You may need to explain your goal.
I am trying to link two tables. So I have data in Table 1 (e.g., email, image) that I want linked to Table 2. I was under the impression this is something I could do in Glide (with Row ID) but maybe not?
As long as you are writing the RowID from Table1 into a column in Table2 whenever you add a new row to that table, then you can simply create a relation between the two linking the RowID in table1 and the written RowID in table2. That’s it.
For example if you are viewing an item from Table1, you can add a form button to add a new row to Table2. In the form you add a Value component which will pass the RowID from table1 into the new row in table2 A relation in one or both tables will link the two together because relations look for a matching value between each table.
RowID is usually recommended because they don’t change, but you can use any value to create a relation as long as both table contain the same values you are trying to match up (ex. email address).
