⭐主要使用el-table的cell-style属性和cell-click事件

1、给el-table添加cell-style属性和cell-click事件

<el-table
	:data="state.dataList"
	style="width: 100%"
	border
	v-loading="state.loading"
	:cell-style="cellStyle"
	@cell-click="cellClick"
>
<!-- 这里写el-table-colum 章小鱼省略-->
</el-table>

2、cellStyle和cellClick方法实现

<script lang="ts" name="" setup>
   const highlightedCell = ref(''); // 控制要高亮单元格标识
   // 单元格颜色
    const cellStyle = ({ row, column }: any) => {
	    if (highlightedCell.value && highlightedCell.value === JSON.stringify(row[column.property])) {
		     return {
			    padding: '5px 0',
			    backgroundColor: 'var(--el-color-primary-light-7)',
		     };
	     } else {
		     return {
			    padding: '5px 0'
		     };
	     }
    };
    // 点击单元格返回
    const cellClick = async (row: any, column: any, cell: any, event: any) => {
	    // console.log(row[column.property], row, column, '点击单元格返回');
	    highlightedCell.value = JSON.stringify(row[column.property]);
    };
    
</script>
