Row summaries are useful, yet not right.
1. If I have a numeric column (of, say, money) and the sum is zero, then instead of showing $0 in the row summary, the table displays " " (blank). The column should display $0.
2. In configuring row summaries, there is no identifier to indicate which column I want to be summarized. If I have a table with 5 numeric columns, but only need one of them summarized, I can't select just that column. The row summaries configuration just lets me change the row-title and the operation (sum, count, average, ..)
Please add support to select the column, and to show the correct value for a sum of $0.
