Swap table columns in writer

I am on a Mac OSX Using Libre Office 4.2.4.2 using Writer Tables to create english to spanish translations, using 2 column format.

i.e.
1st Column = English
2nd Column = Spanish

but i now need to swap columns to

1st Column = Spanish
2nd Column = English

is there a procedure for this in libre office

Thanks for any info
