You are not placing your table anywhere , Try this way
createContent : function(oController) {
var otable = new sap.m.Table({
id : "employees",
itempress : [ ocontroller.itempress,ocontroller ],
colums:[
new sap.m.column({
width:"1em",
header:new sap.m.label({
text: "Emp ID" })}),
new sap.m.Column({
width:"1em",
header:new sap.m.label ({text: "Name"})}),
new sap.m.Column({
width:"1em",
header:new sap.m.label ({text: "Address"})}),
new sap.m.Column({
width:"1em",
header:new sap.m.label ({text: "Designation"})})
]
});
return new sap.m.Page({
title: "Employee Details",
content: [otable
]
});
}
});
