export default {data() {return {columns,loading：false,tableData:[],selectedRowKeys:[]}}computed: {rowSelection() {const { selectedRowKeys } = this;const _this = this;return {selectedRowKeys,  // 一定要加上这一行代码，清除才会有作用onChange: (selectedRowKeys) => {_this.selectedRowKeys = selectedRowKeys;},};},},methods:{clearData () {this.selectedRowKeys = [] // 操作完之后再调用这个方法就有效果了}}
