Thank you for your interest in Syncfusion products.
On analyzing the attached template document we are able to find “TableEnd” mail merge field (TableEnd:Employees) is placed at end of each column and “TableStart” is missing. In order perform mail merge within a table, kindly use “TableStart” merge field as first item of first cell and “TableEnd” merge field as last item of last cell of particular row. If your requirement is to perform mail merge in two columns (i.e., first set of data in first column and second set of data in second column, then move to next row and so on), kindly insert a NEXT field in second column before merge field (NEXT field denotes to move to next record and start mail merge with next set of records).
For more information regarding mail merge functionality of DocIO, kindly refer our UG documentation from below link.
