    that.getView().byId("test") this will give you template, it is not the actual button in the cell. each cell is a copy  of that template.

better to use data binding to enable or disable the button.

    Do it through a model property:

    <Button id="EditButtonID" enabled="{yourLocalModel>/IsRowEditable}" >

    You will probably want the Edit Button to be enabled only if ONE SINGLE row is selected, therefore, use the table's "rowSelectionChange" event, and the code would be like this:

     onRowSelectionChange: function (oEvent) {
 var oTable = oEvent.getSource();
 var bIsRowEditable = !!(oTable.getSelectedIndices().length === 1);
 this.getModel("yourLocalModel").setProperty("/IsRowEditable", bIsRowEditable);
 },

      Hello Artyom,

      Thanks for your input.

      I have tried the above functionality but it is not working.

      Can you please guide me on this or provide me a sample application so that i can refer to.

      ::::Worklist.contrller.js(syntax):::
onInit: function () {
                var oViewModel,
                    iOriginalBusyDelay,
                    oTable = this.byId("table");
                   oTable.attachSelectionChange(this.onRowSelectionChange, this);
      
onRowSelectionChange: function (oEvent) {
                var oTable = oEvent.getSource();
                var bIsRowEditable = !!(oTable.getSelectedIndices().length === 1);
                this.getModel("worklistView").setProperty("/IsRowEditable", bIsRowEditable);
            },

)
:::::::Worklist.view.xml(syntax):::
<Button icon="sap-icon://edit" enabled="{worklistView>/IsRowEditable}" id="test"></Button>

    Check the below plunker example . You need to do this with the help of binding.

    In worklistcontrller.js

    var that = this;

    then in the onTableSelection function

    var oTable = that.getView().byId("table");
var aSelectedItems = oTable.getSelectedItems();
if (aSelectedItems.length > 0) {
that.getView().byId("test").setEnabled(true);
}
