How do I change a table in a single column to a table in two columns without splitting the text before the table

I have a table that is 23 pages long on the left half of the pages. I want to split it into two columns to make it 12 pages long. When I do, it splits the text information before the table by narrowing it to the left over that half of the table. How do I maintain the page wide text and divide the table into two columns without affecting the text?

May be so?

  1. Make your table width 100% so there is no room for text.

or

  1. right click on your table, choose wrapping → none
