Hello Georg.

Thank you for your purchase.

When you create a table using the first option (Create a table linked to an existing data source), wpDataTables is used only to display the values from an external source (Excel, CSV, Google Spreadsheet) and it cannot be edited. If you make changes in the source file - it will be shown in the table. However, please note that this file is being stored in the Media Library of your WordPress site, so if you upload a file from your desktop - changing something in that file wouldn't affect the contents of the table created by our plugin. Instead, you need to access the file in ../wp-content/uploads/YEAR/MONTH/your_file.xlsx and then the changes will be visible.

Please note: Once you create a table from an Excel file, changes in this file, 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 table in the wpDataTable plugin will not work, at the moment. If you make any of these changes, please recreate the table again.

I hope this helps.

Best regards.
