How do I get the columns to total under the "Summary" section at the bottom? Using the code from the original answer above the totals for the rows automatically populate but the bottom section to calculate the column totals does not with the code entered here. Instructions say "When you enter or change values in the expense report table, the column and row totals are automatically updated and the column and row totals are formatted to $2$ decimals places with a thousand separators. The overall travel expense total should be shown in currency format."
