i have inserted a table on the left of my page and when ever i try to type to the right it goes into the table how do i stop that

First, you cannot insert data on the right side of table but above or below.
If you want to make such thing, you need to create 2 tables. The first table contains 2 column, and make it as a invisible table by set border size to 0 pixel. Then create another table inside the first column.
