how can I make a border(highlight) foreach cell from that co

Hello! In the project I am using a dhtmlxtreegrid and inside the grid section I have a editable column where the user can insert values. The question is how can I make a border(highlight) foreach cell from that column to indicate to the user that the column is editable?
T.I.A.

The grid has not API to set default css for specific column, but you can define the necessary style directly in CSS


    normal
    editable

Or do it from js code

    grid.loadXML(url,function(){
       grid.forEachRow(function(id){
          grid.setCellTextStyle(id,INDEX,“border-color:red;”);
        })
    })
