Get all the rows of the table

Hi,

     In my example I want to get all the rows of the table. The table has 20 rows. The visibleRowCount is set to 7 and firstVisibleRow is set to 3.

     I have created the table as

     var oTable = new sap.ui.table.Table({

           id: "oTable",

           title: "My Table",

           visibleRowCount: 7,

           firstVisibleRow: 3,

           selectionMode: sap.ui.table.SelectionMode.Single

     });

     I tried to get the rows of the table using the below code

     var table = sap.ui.getCore().byId("oTable");

     var rows = table.getRows();     //     Returns only 7 rows     

    How to get all the rows of the table when the table is populated with a odata service  ?
