Can't make conditional appearance of the button

Hi
​
Please advice, how should I set up Table List tool.
I am going to make toggle button which have to show up "unpublish" on value 1, and "publish" on value 0.
​
My code in state field area looks like this, but does not work. I think the problem is mistake in element identifier $this->data['Data3']['state'] , because this is table and each row changes index number of the array
​

<?php
if ( $this->data['Data3']['state'] == "1" ) { 
echo 'Unpublish';
} else { 
echo 'Publish';
}
?>

Please, help to get it work

if ($this->data("Data3.state")) {
echo "Unpublish";
etc

Still can not get it work.
Is it possible to call {var:list_table#.row.Model.id} from custom php in the cell clause of Table List tool?
​
I am trying write like $this->get("list_table#.row.Model#.field") but does not work
