 * Hi tonygilgilpin,
 * Sorry for the inconvenience,
 * This warning comes up for tables linked to Excel or CSV files when those tables
   don’t have a header for one or more columns.
 * That means that you need to fill the first row in your files with the data because
   this row is used for creating column headers in wpDataTables.
 * My suggestion is to correct this in your file and then create a new wpDataTable.
 * Please note: Once you create a table from an Excel file, changes in this file,
   like:
    1. Changing the column’s name,
    2. Changing the column’s order,
    3. Deleting the column, and
    4. 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.
 * Thank you for understanding.
 * Best regards.
