我有一个简单的表(类型为sap.ui.table.Table),我允许我的用户对元素进行排序,过滤和分组。但是,一旦应用,就不可能删除排序或分组?可以通过在过滤器中输入任何值来删除过滤器,但如何删除排序/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",
}));
这可能看起来很简单,但在表格本身中没有删除任何内容的选项......它是否真的必须通过编程来删除?

是的,只有通过编码才能做到这一点。基本上,您需要清除ListBinding
的排序器和过滤器,然后刷新DataModel
。对于分组,请将Table
和Column
的分组重置为false,重置后,将Table
的分组设置为true。
//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);
我还附上了一个有效的代码片段。请检查一下。

对于 openui5 v1.78.7 :如果要从表中删除这些过滤器,则:
您可以这样做:
var columns = this.byId("tableId").getColumns();
for (var i = 0, l = columns.length; i < l; i++) {
var isFiltered = columns[i].getFiltered();
if (isFiltered) {
// clear column filter if the filter is set
columns[i].filter("");
}
}
您可以使用以下方法清除排序过滤器:
var columns = table.getColumns();
var sortedCols = table.getSortedColumns();
for (var i = 0, l = columns.length; i < l; i++) {
if (sortedCols.indexOf(columns[i]) < 0) {
columns[i].setSorted(false);
}
}
如果有以下任何一项,请确保对行绑定设置后退排序:
table.getBinding("rows").sort(new Sorter(sPath, bDescending));
