Can I Apply Different Formatting to Each Section of a Split Cell?
Yes, while Excel doesn’t allow for different formats within the actual split sections of a cell, there’s a creative workaround. Once a cell is split diagonally, I can simulate different formatting by using text and background colors that contrast each other. This helps in creating a distinct visual separation. For text alignment, I carefully position text in each section so it appears separate, maintaining the illusion of individual formatting.
