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-tableref="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: stringname: stringaddress: 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-errormultipleTableRef.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',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',},

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-tableref="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-tableref="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;}}
}
