I have a Google Spreadsheet that has 6 or 7 columns that are all related. I would like to group them all under one header, to show this relation. Each column would additionally have its own additional header (C1, C2, C3...) For example,
==========================================
Group Name |
==========================================
C1 | C2 | C3 | C4 | C5 | C6 | C7 |
==========================================
| | | | | | |
| | | | | | |
| | | | | | |
| | | | | | |
| | | | | | |
| | | | | | |
Is there a way to do this?
