Hi @TKEnes ,
If you want to edit the value of a field created by the Addcolumns() function, maybe you need to use the ClearCollect() function to store this temporary table. Then you could use the Patch() function to update the collection.
In addition, here are some links that might help you:

If you want to filter this temporary table, try the formula like this:
Filter(AddColumns(DataSource,"NewColumnName",Formula),StartsWith(NewColumnName,TextInput1.Text))
