I have a table with 2 columns. The first contains a string, the second an integer. The second column is set so values can be edited in the table. I can create new entries in the table by pressing a button, which creates a new dataset based on what is already in the table and what is highlighted in another table.
Editing of the cell works as long as the table initially contains some data. However, if the table is blank and I copy a new entry into it, no editing is possible.
