有的时候需要根据后端数据来控制表格的勾选状态，可以用以下方式实现
<el-table max-height='320' border :data="orderProductList" row-key="workOrderCode" ref="orderRefundProductTable" show-summary :summary-method="totalRule"> <el-table-column type="selection" width="55"/> <el-table-column type="index" fixed label="序号" min-width="50" header-align="center" align="center"/> </el-table> this.orderProductList.forEach(row => { if (row.refundOrderSubId != null) { this.$nextTick(function(){ this.$refs.orderRefundProductTable.toggleRowSelection(row); }) }});
