Hello Kostya.

Thank you for your purchase.

If you used the third option to create the table (Create a table by importing data from data source), that table would be editable in wpDataTables, but those changes wouldn't reflect in the source file.

If, however, you used the first option to create the table (Create a table linked to an existing data source), that table will not be editable through wpDataTables, and it is only showing the data from the source file.

You can change the contents of the source file and those changes will be seen in wpDataTables, but once you create the table, the plugin stores a copy of the source file in ../wp-content/uploads/YEAR/MONTH and that's the file you need to modify in order for wpDataTables to display the change.

Once you create a table from a CSV 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.

Best regards.

I see, Kostya.

Thank you for your suggestion. We carefully follow customers requirements and try to implement most of them if they appear in requests from time to time, so we will add to our idea list and look into some possible solutions on plugin side in the future.

Maybe you can consider going for large MySQL query based tables. You can add CSV files to the database using PHPMyAdmin, and tables created linked to an existing file source would update automatically for SQL query based tables.

Best regards.
