Hide subtotal on some row.

Hi,
Have to say that, this tool is great. 
I need help with not showing the subtotal for some of the rows.
As shown in the picture I don’t need to see the subtotal on the highlighted row data.
I only want to see the subtotal of the first row item only.
 
 
var pivot = new WebDataRocks({
container: “#wdr-component”,
toolbar: true,
height: “700”,
customizeCell: customizeCellFunction,
report: {
“dataSource”: {
“dataSourceType”: “json”,
// “browseForFile”: true
“filename”: “periods.json”
},
“slice”: {
“expands”: {
“expandAll”: true
},
“rows”: [
{
“uniqueName”: “plinid”,
“caption”: “Category”
},
{
“uniqueName”: “itmclss”,
“caption”: “Mfr”
},
{
“uniqueName”: “item”,
“caption”: “Part Number”
},
{
“uniqueName”: “itmdesc”,
“caption”: “Description”
},
{
“uniqueName”: “avgcost”,
“caption”: “Avg Cost”
}
],
“columns”: [
{
“uniqueName”: “aging_period”
},
{
“uniqueName”: “Measures”
}
],
“measures”: [
{
“uniqueName”: “aging_qty”,
“aggregation”: “sum”,
“caption”: “Qty”
},
{
“uniqueName”: “aging_amt”,
“aggregation”: “sum”,
“format”: “3n0prh14”,
“caption”: “Amt”
}
]
},
“options”: {
“grid”: {
“type”: “classic”
}
},
“formats”: [
{
“name”: “3n0prh14”,
“thousandsSeparator”: “,”,
“decimalSeparator”: “.”,
“currencySymbol”: “$”,
“currencySymbolAlign”: “left”,
“nullValue”: “”,
“textAlign”: “right”,
“isPercent”: false
}
],
“tableSizes”: {
“columns”: [
{
“idx”: 3,
“width”: 360
}
]
}
},
reportcomplete: function() {
pivot.off(“reportcomplete”);
pivotTableReportComplete = true;
// createGoogleChart();
}
});
function customizeCellFunction(cellBuilder, cellData) {

if (cellData.type == “header”) {
switch(cellData.columnIndex) {
case 1:
case 2:
case 3:
case 4:
cellData.isTotalRow = false;
console.log(cellData);
}
}
}
 
 

Thanks a lot.
