First thing for the single part data is to set up the start cell of the table area.
That is the column number and the row number of the first cell in the table area.

  

 

Next step is to set up the list of single data to be exported.
The left list displays all available data fields.
Move fields to the right list to get them exported.
Starting from the top each field is exported to a column.
There is not check of the template file. Data gets exported as set up in this list no matter how the template looks like.
The up and down button can be used to adjust the order.
For some fields like total weight it is possible to activate the sum.

For this column the sum formula will be inserted automatically into the summary row at the end of the table.
