Session Table Control

I found this recently and greatly appreciate the code. It has made monitoring a table very easy. I do have one caution to anyone else using it. The act of refreshing the edit display to see what is in the table, resets the timeout. In my case,. I did not want the observation of the table to reset the time. I added -notouch to the line

foreach key [table keys -notouch -subtable $tname] {

(line 133 above). I also added -notouch to line 135 so it reads

append resp "<td class='tvalue'>[table lookup -notouch -subtable $tname $key]</td>";
