When reading larger spreadsheets, it would be helpful to highlight the row and column that the currently selected cell is in. I'm not talking about conditional formatting or anything in the spreadsheet itself, I'm just talking about a viewing option. I couldn't find a similar option anywhere.
If I understand your question, Numbers does this by default - note the darkened row and column identifiers in the image below at AK50.
Edit: ah, I see.. okay, I found an inconvenient hack:
- Select the Column containing your target cell
- Cmd click the cell above (or the Cmd Click the row index of the cell above)
- Cmd click the Row containing your target cell
- Cmd click to reselect the cell above your target
Maybe you could use automator to make this less painful?
