User Problem: Why doesn’t Excel offer horizontal subtotals (see Figure1, below)?
Solution: This is a great question. I had several people write in to say that they regularly
used the following method to add horizontal subtotals. Although it is a lot of steps, if you use shortcut keys, it is actually fast.
1). Select the original data with Ctrl+*.
2). Go a few rows below the data. Paste with Alt+E+S+E+Enter.
3). Alt+D+B to display the Subtotals dialog. Click OK.
5). Select cell A1.
6). Paste Transpose with Alt+E+S+E+Enter.
7). Fix the column widths with Alt+O+C+A (see Figure 2, left).
8). Delete the temporary table at the bottom.
9). Optionally, select columns B:D and choose Data, Group.
11). Repeat step 10 for J:L and N:P.
12). Select B:Q and choose Data, Group. You now have collapsible horizontal subtotals
(see Figure 3).
