Replace table row cell[1] text with cell[0]

Hi Forum,

Thanks for your support so far. I have come up with new request, please anyone there to quench by thirst;

actually i want to replace, cell[1] of the every rows of every table with cell[0] of every rows of every table.

I dont think its a right way of doing this like i doing now;;

myPage =app.activeDocument.pages.everyItem();

var mytable =myPage.textFrames.everyItem().tables.everyItem().columns[0];

mytable.remove(myPage.textFrames.everyItem().tables.everyItem().column s[1]);

myPage.textFrames.everyItem().tables.everyItem().convertToText("\t","\ r");

Also, i tried in this way.... but script find only the first instance and replace... and not the next cell[1] with cell[0] on next row..

myPage =app.activeDocument.pages.everyItem();

var mytable =myPage.textFrames.everyItem().tables.everyItem();

var c1 =mytable.rows.everyItem().cells[0].contents;

var c2 = mytable.rows.everyItem().cells[1].contents;

app.changeTextPreferences = null;

   app.findTextPreferences.findWhat =c1;

   app.changeTextPreferences.changeTo =c2;

   app.changeText();

please help on this..
