Hi Robin,
I've tried but it doesn't work ... the table shows key, no description ...... below is my code ....
oTable.addColumn(new sap.ui.table.Column({
label: new sap.ui.commons.Label({text: "test 2"}),
template: new sap.ui.commons.ComboBox({selectedKey: "test", items: [
new sap.ui.core.ListItem({text: "City 1", key: "1"}),
new sap.ui.core.ListItem({text: "City 2", key: "2"}),
new sap.ui.core.ListItem({text: "City 3", key: "3"})
]}).bindProperty("value","test") }));
