When you have a table like the one below and you want to add a column either left or right of the selected one, it will always be added relative to the first column in the table no matter what you have selected. unlike adding rows to tables, which are added relative to your current selection. In this example case Add Column Right would always add a column to the right of column A. Add Column Left would add a column to the left of column A until column A is no longer the first column, after which the new column will become the first column and all subsequent columns that are added will be relative to the new one.
