model.setColumns(["ID", "User Name", "Sex", "Age"]);

    ['1', 'Zhangsan', 'man', 17],
    ['2', 'Lisi', 'man', 23],
    ['3', 'Wanger', 'man', 25],
    ['4', 'Mazi', 'man', 20],
    ['5', 'Chunhua', 'woman', 18]
]); 

var table = new qx.ui.table.Table(model);
table.set({
    width: 600,
    height: 400
}); 

table.getSelectionModel().setSelectionMode(qx.ui.table.selection.Model.MULTIPLE_INTERVAL_SELECTION); 

this.getRoot().add(table, { left: 20, top: 50 });
