What can I do if get error “Please provide a valid 2-dimensional array”?By Milan Jovanovic on 23/07/18 in
You are probably getting this error because you have formatting in that spreadsheet. Can you please remove that formatting from a file, because when you make wpDataTables you can adjust the look of the table and arranged data how you want. Please note that merge cells can also produce this issue because at the moment they are not supported in wpDataTables.
