Example of User-Defined Sections for Reports
User-defined sections are useful when you want to combine column types.
For example, if you want to combine standard columns and grid columns in the same report, you set up a user-defined section for the standard columns and another section for the grid columns, and then assign the columns of each type to the appropriate section.
You cannot mix grid columns with vertical (non-grid) columns in a single section.
You cannot mix grid columns from different grids in the same section. Use the Type column to determine the grid to which a column belongs.
