I have part numbers in a table and when I try to cut and paste multiple cells
in a table, word will strip out all the the dashes and information to the
right of the dash.

so instead of

12345-001
45678-003
54321-004
I get

12345
45678
54321

after I paste into the table. Oddly if I paste all the numbers into 1 cell
the dash numbers don't disapear, but that doesn't help much.
