Possible to enter data in both sides off a diagnal bordered split?

[godwint]

I'm trying to enter data on both sides a cell that has a formatted border
split diagonaly. Is it possible to enter data in both sides off a diagnal
bordered split cell? Color and data.

You can't colour the two sides differently. To make text appear on each
side you could:
Type the heading for the left side
Press Alt+Enter, to create a line break
Type some spaces, then type the right heading

Or, on the Drawing toolbar, select AutoShapes>Lines
Select the Freeform tool, and draw a triangle over each side.
Colour the triangles, and enter the heading text in each.
