Thank you for you answer.

I have not try the AutoText command, but I will look in this direction,
thank you.
No, I can't replace the table by text, because I have many things on those
table cells like check boxes, entry... who need to be formated precisely
(hard to explain).

That's clear, deleting the table will cause it to be completely lost.

The current point where I am is to put the checkbox in the first cell of
each table and delete all the row, but not the first, when the checkbox
become false. This is to memorize the position of the table in the
document.
And when the checkbox become true again, I try to insert the old rows after
the remaining one. But an other problem appear, it is when I insert the new
rows, they are created every time BEFORE the single row (by copy/paste).
I don't want to delete the row with the checkbox because, of course, I will
loose the link with the code.

What does I have to do to be sure that the new rows will be inserted AFTER
the single table row ?
