I've inserted a table (fm7 nonstructured) and populated the rows and find that some are "footing rows". Can the "footing rows" be converted to body rows? 
I'm not finding/understanding the book/help regarding the i)utility, ii) table creation behavior, iii) formating options available and iv)persistance of these "footing rows". 
I created the table with 3 heading rows: three footing rows appeared below a double rule after the last body row. The body rows were 3 short of the number that I asked for when inserting the table.  
I've inserted fresh rows at the end of the body rows and moved the data that populated the "footing rows" to the newly inserted body rows. I then tried to delete the "footing rows" by highlighting all 3 and get the message "Cannot delete all body rows from a table that has heading and footing rows". Sucessfully deleted 2 of the three by selecting one row at a time, but the third "footing row" will not delete with the same error message as above when deletion attempted. 
I could use some enlightenment to become table savy.
