The first column format is defined by the WorksheetTableStyle applied to the WorksheetTable. It is stored in the WorksheetTableStyle.AreaFormats collection and keyed by the WorksheetTableStyleArea.FirstColumn value. If there is no area format applied for the FirstColumn value, this property has no effect on the display of the table.
If there is only one column in the table and both the first and last column formatting should be applied, the last column format will take precedence.
