How to fix ladder tables in word 2007?

Question

Word

There is a table, in the cell of this table there is another table, I set a bookmark on row 2 of the table and in the script in the cycle I "clone" this bookmark several times to get the necessary table with the required number of rows. The problem is that the lines after generation line up with a ladder, and not one under the other, I tried alignment and so on, but nothing comes out.
