Element UI 表格组件复选框实现单选效果

需求：el-table表格复选框限制只能选中一条。

具体代码实现如下：

<template>
    <el-table ref="tableRef" :data="tableData" border @selection-change="handleSelectionChange" header-cell-class-name="headerCellClass">
        <el-table-column  type="selection" width="55"></el-table-column>
        <el-table-column prop="date" label="Date" width="180" />
    	<el-table-column prop="name" label="Name" width="180" />
    </el-table>
</template>

<script setup>
let selectData = ref([]);
const tableRef = ref({});
const handleSelectionChange = (select) => {
	if(select.length > 1) {
	    // 清除所有勾选框
		tableRef.value.clearSelection();
		selectData.value = select.pop();
		// 勾选当前选中的数据
		tableRef.value.toggleRowSelection(selectData.value, true)
	}
}
</script>

去掉表头全选勾选框

给el-table绑定类名：header-cell-class-name=“headerCellClass”

:deep(.headerCellClass){
	.el-checkbox{
		display: none;
	}
}
