 * Hi there,
 * This error refers when there are some changes in the file from which table is
   created.
 * Can You please tell me if You changed something directly in the database? Column
   name, type, content, did You add something? Whatever comes to mind.
 * Best regards.

 * Hi,
    Thanks for the reply.
 * No, I just uploaded an excel sheet and it was showing a blank one in the preview
   and frontend. So I uploaded that file again. When I did that 2-3 times, it showed
   this error.

 * Hello again.
 * When you say you uploaded the Excel file – you mean created a table by using 
   the third option (Create a table by importing data from data source), correct?
 * If so, when you get to the preview part of the table, please inspect the column
   headers. If there is an empty header, an issue like this can occur.
 * Best regards.
