What Suzanne told you should work (at least as far back as Word 97) but I
would refine it slightly
1. Same
2. Same
3. Same (easy way to add the second row to the selection is to press shift
and down arrow)
4. Just select 3 rows here (again shift and down arrow adds extra row to
selection)
5. (not needed - you have ten rows)
An alternative if your table is regular is to position the cursor
immediately below the table and insert a 10 row by 6 column table which Word
will join with your existing one - key strokes are Alt+a, i, t, 6, tab, 1,
0, enter.
