how to get the field name inside an styler function?

[r2ferna]

Hi:

I am adding some fields (31) to a datagrid. They are added dynamically depending on user inputs.
I want to use just one styler function for all the 31 fields, but I need the field-name to make decisions inside the styler code.

The styler function recives only three parameters:
 value: the field value.
 rowData: the row record data.
 rowIndex: the row index.

How can I send the field-name?
I have tried the next with no luck:

Code:

    function modificaGrid(){
    	var numDias = $('#inpDiffDays').val();
        var jsDate = js2_parserDate( $('#inpFechaD').datebox('getValue') );
        var newCols = [];
        for (i=1;i<=numDias;i++) {   /* numDias = 31 */
            var campo = 't-eh-&1'.replace('&1',i);
            var diaAlfa = js2_weekDay(jsDate);
            var title = '&1 &2-&3'
                .replace('&1',diaAlfa.substr(0,2))
                .replace('&2',('0'+(jsDate.getMonth()+1)).slice(-2))
                .replace('&3',('0'+jsDate.getDate()).slice(-2));
            var col = {
                    field:campo, title:title, width:60, align:'center',
                    styler:function(value,row,index){ console.log('inside styler: ', campo); 
                               local_tehStyler(value,row,index,campo);
                     },
                     /* here: campo inside styler  = the last value (t-eh-31), but every field value is OK!! */
                };
            newCols.push(col);
            jsDate = js2_addDaysToDate(jsDate,1);
        }
        var cols = g_dfltCols.concat(newCols); newCols=[];
        console.log(cols);
        $('#dg').datagrid({columns:[cols]}); cols=[];
    }

with this code:

Code:

   styler:function local_tehStyler(value,row,index,campo){console.log('inside styler: ', campo);},

the campo is undefined!

The styler function is something like:

Code:

function local_tehStyler(value,row,index,campo){
        var numColor = null;
        console.log(campo);
        var numField = last-part-of-the-field-name(campo);
        var anotherField = 't-por-&1'.replace('&1',numField);
        var tpor = row[anotherField]; 
        if (tpor=='R') numColor=14; else if(tpor=='W') numColor=6; else if (tpor=='M') numColor=12
        else if(tpor=='O') numColor=13;
        return 'background:&1;'.replace('&1',js1_traduceNumColor(numColor));
      }

MTIA.
