最终用户如何清除网格列的排序？

Question

I use ExtJs 6.6.0 Classic. Thegrid component supports multi-column sorting (I use remoteSort: true, remoteFilter: true). Whenever the user clicks on a column header, that column becomes the first column in the order by list. But I cannot find how an end user is supposed to clear the sorting for a column. The context menu available through the column header doesn't have a "Clear Sort" option.

See also this kitchensink example .

I feel like I am missing something. There is a sortClearText config for the column inherited from the header, but I could not find a place where it's used (I thought that perhaps there is some config I can use to add the Clear Sort menu item to the column context menu).

I could add a button to execute the action of clearing the sorting of the store, as a last resort, but I don't like it.

Is there a simple way to add a Clear Sort option for a grid column through the Extjs components configuration?

Thank you

I also did not find, but you can use the following override:

Ext.define('overrides.grid.header.Container', {
    override: 'Ext.grid.header.Container',
    
    getMenuItems: function() {
        var me = this,
            menuItems = [],
            hideableColumns = me.enableColumnHide ? me.getColumnMenu(me) : null;
 
        if (me.sortable) {
            menuItems = [{
                itemId: 'ascItem',
                text: me.sortAscText,
                iconCls: me.menuSortAscCls,
                handler: me.onSortAscClick,
                scope: me
            }, {
                itemId: 'descItem',
                text: me.sortDescText,
                iconCls: me.menuSortDescCls,
                handler: me.onSortDescClick,
                scope: me
            }, {
                itemId: 'dropSortItem',
                text: me.sortClearText,
                //iconCls: me.menuSortDescCls, // Your icon
                handler: me.onSortClearClick,
                scope: me
            }];
        }
 
        if (hideableColumns && hideableColumns.length) {
            if (me.sortable) {
                menuItems.push({
                    itemId: 'columnItemSeparator',
                    xtype: 'menuseparator'
                });
            }
 
            menuItems.push({
                itemId: 'columnItem',
                text: me.columnsText,
                iconCls: me.menuColsIcon,
                menu: hideableColumns,
                hideOnClick: false
            });
        }
 
        return menuItems;
    },
    
    onSortClearClick: function() {
        var menu = this.getMenu(),
            activeHeader = menu.activeHeader,
            store = this.up('grid').getStore();
        store.getSorters().each(function(sorter) {
            if(sorter.initialConfig.property == activeHeader.dataIndex) {
                store.getSorters().remove(sorter)
            }       
        }, this);
    }
});
