Ⅰ、Element-plus 提供的 Table 表格组件与想要目标情况的对比：
1、Element-plus 提供 Table 组件情况：
其一、Element-ui 自提供的 Table 代码情况为(示例的代码)：
// Element-plus 自提供的代码：
// 此时是使用了 ts 语言环境，但是我在实际项目中并没有使用 ts 语言和环境；
<template>
<el-table
ref="multipleTableRef"
:data="tableData"
style="width: 100%"
@selection-change="handleSelectionChange"
>
<el-table-column type="selection" width="55" />
<el-table-column label="Date" width="120">
<template #default="scope">{{ scope.row.date }}</template>
</el-table-column>
<el-table-column property="name" label="Name" width="120" />
<el-table-column property="address" label="Address" show-overflow-tooltip />
</el-table>
<div style="margin-top: 20px">
<el-button @click="toggleSelection([tableData[1], tableData[2]])"
>Toggle selection status of second and third rows</el-button
>
<el-button @click="toggleSelection()">Clear selection</el-button>
</div>
</template>
<script lang="ts" setup>
import { ref } from 'vue'
import { ElTable } from 'element-plus'
interface User {
date: string
name: string
address: string
}
const multipleTableRef = ref<InstanceType<typeof ElTable>>()
const multipleSelection = ref<User[]>([])
const toggleSelection = (rows?: User[]) => {
if (rows) {
rows.forEach((row) => {
// TODO: improvement typing when refactor table
// eslint-disable-next-line @typescript-eslint/ban-ts-comment
// @ts-expect-error
multipleTableRef.value!.toggleRowSelection(row, undefined)
})
} else {
multipleTableRef.value!.clearSelection()
}
}
const handleSelectionChange = (val: User[]) => {
multipleSelection.value = val
}
const tableData: User[] = [
{
date: '2016-05-03',
name: 'Tom',
address: 'No. 189, Grove St, Los Angeles',
},
{
date: '2016-05-02',
name: 'Tom',
address: 'No. 189, Grove St, Los Angeles',
},
{
date: '2016-05-04',
name: 'Tom',
address: 'No. 189, Grove St, Los Angeles',
},
{
date: '2016-05-01',

2、目标想修改后的情况:
Ⅱ、实现 Table 表格组件达到目标效果变化的过程：
1、 Table 表格组件成功引入 vue3 项目的过程(去除了 ts 的语法)：
其一、代码：
<template>
<el-table
ref="multipleTableRef"
:data="tableData"
style="width: 100%"
@selection-change="handleSelectionChange"
>
<el-table-column type="selection" width="55" />
<el-table-column label="Date" width="120">
<template #default="scope">{{ scope.row.date }}</template>
</el-table-column>
<el-table-column property="name" label="Name" width="120" />
<el-table-column property="address" label="Address" show-overflow-tooltip />
</el-table>
</template>
<script setup>
import { ref } from 'vue'
const tableData =ref([
{
date: '2016-05-03',
name: 'Tom',
address: 'No. 189, Grove St, Los Angeles',
},
{
date: '2016-05-02',
name: 'Tom',
address: 'No. 189, Grove St, Los Angeles',
},
{
date: '2016-05-04',
name: 'Tom',
address: 'No. 189, Grove St, Los Angeles',
},
{
date: '2016-05-01',
name: 'Tom',
address: 'No. 189, Grove St, Los Angeles',
},
{
date: '2016-05-08',
name: 'Tom',
address: 'No. 189, Grove St, Los Angeles',
},
{
date: '2016-05-06',
name: 'Tom',
address: 'No. 189, Grove St, Los Angeles',
},
{
date: '2016-05-07',
name: 'Tom',
address: 'No. 189, Grove St, Los Angeles',
},
])
</script>
<style lang="scss" scoped>
</style>
其二、效果展示：
2、 调整 Table 多选框的样式及整体 table 表格样式的代码为：
其一、整体代码为：
<template>
<div class="my_project">
<div class="project">
<el-table
ref="multipleTable"
:data="tableData"
style="width: 1000px"
:row-class-name="tableRowClassName"
>
<el-table-column type="selection" width="55" />
<el-table-column label="Date" width="120">
<template #default="scope">{{ scope.row.date }}</template>
</el-table-column>
<el-table-column property="name" label="Name" width="120" />
<el-table-column property="address" label="Address" show-overflow-tooltip />
</el-table>
</div>
</div>
</template>
<script setup>
import { ref } from 'vue'
const multipleTable = ref('')
const tableData =ref([
{
date: '2016-05-03',
name: 'Tom',
address: 'No. 189, Grove St, Los Angeles',
},
{
date: '2016-05-02',
name: 'Tom',
address: 'No. 189, Grove St, Los Angeles',
},
{
date: '2016-05-04',
name: 'Tom',
address: 'No. 189, Grove St, Los Angeles',
},
{
date: '2016-05-01',
name: 'Tom',
address: 'No. 189, Grove St, Los Angeles',
},
{
date: '2016-05-08',
name: 'Tom',
address: 'No. 189, Grove St, Los Angeles',
},
{
date: '2016-05-06',
name: 'Tom',
address: 'No. 189, Grove St, Los Angeles',
},
{
date: '2016-05-07',
name: 'Tom',
address: 'No. 189, Grove St, Los Angeles',
},
])
// 设置 table 表格中不同行的背景颜色;
const tableRowClassName = (val) => {
if(val.rowIndex %2 === 0){
return 'double-row'
} else {
return 'single-row'
}
}
</script>
<style lang="scss" scoped>
.my_project {
margin: 30px auto;
background-color: #c7cacf; // 设置整体的背景色(即：表格外的背景颜色);
box-shadow: rgba(0, 0, 0, 0.15) 0px 0px 40px 0px;
// 设置表格表头的背景色;
::v-deep(.el-table th) {
background-color: rgb(154, 201, 207);
}
// 表格表头的下边框；
::v-deep(.el-table th.is-leaf) {
border-bottom: 1px solid #557A95;
font-weight: 700;
font-size: 16px;
color: black;
}
// 取消多选第一列的展示;
// ::v-deep(.el-table th.el-table__cell:nth-child(1) .cell) {
// visibility: hidden;
// }
// 将表格的每一行悬停的背景色都设置为：transparent(即：没有其他展示)，或其它颜色(如：yellowgreen) ;
::v-deep(.el-table--enable-row-hover .el-table__body tr:hover > td) {
background-color: #8fd4d9;
}
// 设置表格内双行的背景色(如：0,2,4........)
::v-deep(.el-table .double-row) {
background-color: #e6f1f9;
}
// 设置表格内单行的背景色(如：1，3，5.......)
::v-deep(.el-table .single-row) {
background-color: #d6e6f5;
}
.project {
margin: 20px;
}
}
// 修改多选框的样式;
.el-table {
::v-deep(.el-checkbox__inner){
// 此时是：设置多选框的长度和宽度，以及背景色;
--el-checkbox-input-height: 21px !important;
--el-checkbox-input-width: 20px !important;
background-color: #ccc;
// 此时是：调整选中得对勾得位置;
&:after {
top: 5px;
left: 7px;
}
}
}
</style>
