It is seem to be newbie question. But I don't know how to generate the N x M grid in draw.io
My current solution for 3x3 grid:
Step 1. Draw 9 squares
Step 2. Drag-and-drop them into grid formation.
However, this method does not scale very well. If I want to draw 9x9 grid, it is take a lot of time.
Is there any better way ?
