There is not a column that will show gift types.
The columns in the Gift Detail and Summary Report are based on gift types.
Here is an alternative option:
1. Go to the Gift Types tab (Each column includes certain gift types)
2. Select gift type to be included in each column (example: cash gift in column 1, pledges in column 2, pledge payments in column 3 etc.)
3. Rename column name to correspond with the gift type included
4. Preview report (the gift types will show in the separate columns)
