How to calculate table COLUMN total

Hello

I've been able to calculate row totals for each column but now I'd like to calculate a total per column for all the rows in the table.

So say if i had a table with columns mon-fri

I'd have some form of a footer with a total then for mon, and another for tues, and another for wed, etc..

    Hi,

    This might help.

    var oTable= sap.ui.getCore().byId("<<Table Id>>");

    var nRows= oTable.getBinding("rows").getLength();

    var nSum= 0;

    for(var i=0; i<nRows; i++){

    var oContext= oTable.getContextByIndex(i);

    nSum+= oContext.getProperty("<<Col Name as defined in the model>>");

    }

    Here I am assuming that the data type of columns "Mon", "Tues" in the model is of type 'Number'.

    Regards,

    Aditya

      I think what's happening is that the model isn't ready binding the table because my code is very similar to yours but I have to put an alert in the $( document ).ready function for it to work, so with the alert in it works fine.

      init: function(){ var oUrl = 'http://restservice/data/get_data'; var oParams = {"WEEK_ENDING":"20140302"}; var oModel = new myJSONModel; oModel.loadData(oUrl, oParams, true, 'POST', false, false, ''); //This works sap.ui.getCore().setModel(oModel); oModel.setSizeLimit(1000); }, onInit: function() {

      this.init();

      var that=this;

      $( document ).ready(function() {

      alert("doc ready");

      that.handlePressMonday();

      });

      },
