Hello Arnaud, welcome to Glide’s community forum.
A few random ideas:
-
Are you sure you need to copy data from one table from another? If possible I would consider other options first.
-
Table architecture. Imagine I’m creating a Things tab on which I will display a collection of Things. In the Data Editor, I create a table called Things Tab and don’t touch it (I might touch it at the outset). I create a second table called Things Collection where I will store data related to the Things collection. Each of my tabs have their own table, each of my collections have their own table, and I keep these tables strictly separate.
-
One-off methods to copy data. You can right-click on any table and duplicate it. You can right-click on any table and do a data import. You can select cells in one table and copy-paste them into another. Below the Users table, you can import a file.
-
As long as the style of a tab is custom, any collection, and therefore any table, can live on any tab via a collection component.
-
Fetching data from another table. You can leverage the Single Value column. In the destination table (the table you are copying the data to):
- Create a dynamic RowIndex column: RowID column, lookup of RowID column, find element index of RowID column.
- Create a Single Value column to pull in a column from the origin table: Single Value column, from start, RowIndex, column from the original table.
- Repeat with Single Value columns to fetch additional columns.
I hope this helps.
