Is it possible to insert a new column or row in Adobe Illustrator's graph data editor? (without having to move the existing data through Ctrl + X, Ctrl + V)
I use Adobe Illustrator CC 17.0.0 64-bit on Windows 7 SP1 x64 Ultimate.
I don't believe you can specifically insert a row or column.
You can click-drag to highlight multiple cells and copy. Then click-drag to highlight new cells and paste. You don't have to copy/paste one cell at a time.
