dhtmlXGrid query cntr excell

Dear support team,

We have cntr type column in our grid.

How can we set this counter to start counting from second or third or any further row except first?



There is no built in API for such use-case, the only way - code modifications
You can update code of dhtmlxgrid_excell_cntr.js in next way
    line 48
cell.innerHTML = val;      
    can be rewritten as       
if (val==1) cell.innerHTML = “”;
else cell.innerHTML = val-1;
