title: SAPUI5 column summing
body: <p>I developed a SAPUI5 table on frontend having 4 columns, now I need to show the total sum of 1 column. If anyone knows the code related to this please help me</p>
  
  <p>Controller code</p>
  
  <pre><code>onInit: function () {
  var oTable = this.byId("producttable"); 
  oTable.addStyleClass("myCustomTable");  
      //column list item creation
      var oTemplate = new sap.m.ColumnListItem({
          cells: [
              new sap.m.Text({
                  text: "{Plant}"
              }),
              new sap.m.Text({
                  text: "{PlantDesc}"
              }), 
              new sap.m.Text({
                  text: "{parts: [ {path: 'NetAmount'}, {path: 'currency'}],type: 'sap.ui.model.type.Currency',formatOptions: {showMeasure: false, maxFractionDigits: 0,roundingMode: 'away_from_zero'}}"
              })
           ]
      });
      var sServiceUrl = "/sap/opu/odata/sap/ZSALES_PLANT001_SRV/";
      //Adding service to the odata model
      var oModel = new sap.ui.model.odata.ODataModel(sServiceUrl, false);
      //Setting model to the table
      oTable.setModel(oModel);
      oTable.bindAggregation("items", {
          path: "/ZSalesheaderSet",
          template: oTemplate
      });
  </code></pre>
