dot*_*huZ 4 sorting grouping filter sapui5
我有一个简单的表(类型sap.ui.table.Table),允许用户对元素进行排序,过滤和分组。但是,一旦应用了排序或分组功能,就不可能删除它吗?可以通过在过滤器中不输入任何值来删除过滤器,但是如何删除排序/分组?
var oTableEmpl = new sap.ui.table.Table({
width : "100%",
visibleRowCount : 20,
selectionMode : sap.ui.table.SelectionMode.Multi,
navigationMode : sap.ui.table.NavigationMode.Scrollbar,
editable : false,
enableCellFilter : true,
enableColumnReordering : true,
enableGrouping : true,
extension : oMatrixLayout,
});
oTableEmpl.addColumn(new sap.ui.table.Column({
label : new sap.ui.commons.Label({
text : "Label",
textAlign : sap.ui.core.TextAlign.Center
}),
template : new sap.ui.commons.TextView({
text : "{Value}",
textAlign : sap.ui.core.TextAlign.Center
}),
visible : false,
sortProperty: "Value",
filterProperty: "Value",
}));

这似乎很容易,但是在表本身中没有删除任何东西的选项。确实需要通过编程来删除它吗?
是的,只有通过编码才能做到这一点的方法。基本上,您需要清除的排序器和过滤器ListBinding,然后刷新DataModel。对于分组,重新的分组Table,并Column以虚假的,复位后,设置的分组Table回真。
//set group of table and column to false
oTableEmpl.setEnableGrouping(false);
oTableEmpl.getColumns()[0].setGrouped(false);
var oListBinding = oTableEmpl.getBinding();
oListBinding.aSorters = null;
oListBinding.aFilters = null;
oTableEmpl.getModel().refresh(true);
//after reset, set the enableGrouping back to true
oTableEmpl.setEnableGrouping(true);
