el-table的复选框格子很小每次点击都点不到，又不想设置行点击，因为每次复制内容都会选中，实现效果是点击el-table的复选框单元格就可以选中
<template><div style="width: 60vw; margin: 10px;"><el-table :data="state.tableData" ref="multipleTableRef" @selection-change="handleSelectionChange" border><el-table-column type="selection" width="55" :class-name="'all-selection'" /><el-table-column type="index" label="序号" width="55" align="center" fixed />// 如果某一行的内容超出的话添加超出省略 show-overflow-tooltip 或者增大复选框的高度<el-table-column label="姓名" prop="name" align="center" show-overflow-tooltip/><el-table-column label="年龄" prop="age" align="center" /></el-table></div>
</template><script setup>
import { ref, reactive, onMounted } from 'vue';
// 表格ref
const multipleTableRef = ref();
// 存放选中数据
const multipleSelection = ref();const state = reactive({tableData: [{name: '张三',age: 1,},{name: '张四',age: 2,},{name: '张五',age: 3,},],
});onMounted(() => {});// 选中的回调
const handleSelectionChange = (val) => {multipleSelection.value = val;
};
</script><style scoped lang="scss">
:deep(.el-table__body) {.all-selection {.cell {// 宽度设置满格width: 100%;// 去掉原有的paddingpadding: 0;// 这个是关键，height需要设置为你表格里最大高度height: 40px;.el-checkbox {height: 100%;width: 100%;padding-left: 10px;}}}
}
</style>
