Hello Frank

Thank you for your interest in our plugin.

Please note: Once you create a table from a Google Spreadsheet, changes in the core file from which a table is created, like:

• Changing the column’s name,
• Changing the column’s order,
• Deleting the column, and
• Adding a new column.

are highly not recommended, because the old table will not work, at the moment. If you make any of these changes, please recreate the table again

So, if you wish to add new columns to a Google Spreadsheet and have that displayed in wpDataTables, you would need to create a new table in the plugin.

Best regards.
