Use ^ notation to visually merge cells vertically (like rowspan in HTML tables).
How it works
Cell Content
Display
^ (only)
Merges with cell above (border removed, content hidden)
\^
Shows as ^ character (escaped)
text^text
Shows as-is (no merge)
Example
| Header |
|--------|
| Value |
| ^ |
| ^ |
This displays as a single merged cell spanning 3 rows.
Notes
^ in the first row (no cell above) displays as ^ text
Multiple consecutive ^ cells form one large merged cell
All operations (selection, editing, copy/paste) work normally
