createIfNull

True to create the hidden column if it has not yet been allocated of the Worksheet. The options will be initialized based on the current state. Note the options should only have been null if there were no options for the Worksheet when the Workbook was loaded. Also this will not allocate the collection unless the SaveHiddenRowsAndColumns is true.

Exceptions
