How can I get some example of drawing a matrix or table in OpenGL??? Then I want to select a column of that table to draw a ball inside.
For example I select the cell 2x4 of the table, and in that position it’s draw a ball or sphere.

How can I do this? Or where can I get some example?

Or a 3D version here:

Or the nicer looking one here:
