I have implemented multi-row grouping with totals in the headers, but I am facing an issue where empty rows are displayed instead of the totals rows. How can I remove these unwanted totals rows from my grid? Thank you!
.cshtml:
<div id="gridList" class="grid" style="width: 100%; height: 500px"></div>
.js
$(function() {
var columns = [

editor: Slick.Editors.Checkbox, sortable: true
},
{
id: "symbol",
name: "Symbol",
field: "symbol",
sortable: true /*, width: 120*/
},
{
id: "price",
name: "Price",
field: "price",
sortable: true
//, groupTotalsFormatter: sumTotalsFormatter
},
{
id: "parent_name",
name: "Parent Name",
field: "parent_name",
sortable: true /*, width: 120*/
