vue3+ts 结合el-table二次封装表格组件_export interface tabledata {}

效果图

 Table组件

<template>
  <el-table :data="tableData" style="width: 80%" v-bind="{ border: true }">
    <el-table-column type="selection" width="50" align="center" />
    <el-table-column type="index" label="序号" width="100" fixed="left" align="center">
      <template #default="{ $index }">
        <i>{{ $index + 1 }}</i>
      </template>
    </el-table-column>
    <el-table-column
      v-for="col in option"
      :key="col.prop"
      :label="col.label"
      :prop="col.prop"
      :width="col.width"
      :align="col.align"
      v-bind="{ ...col.attrs }"
    >
      <template #header>
        <!-- <span v-if="col.editable"><button>可编辑</button></span> -->
        <span>{{ col.label }}</span>
      </template>
      <template #default="{ row, $index }" v-if="col.slot">
        <slot :name="col.slot" :row="row" :index="$index"></slot>
      </template>
    </el-table-column>
  </el-table>
</template>
 
<script lang="ts" setup>
import { TableOption, TableData } from './tableData'
type Props = {
  option: Array<TableOption>
  tableData: Array<TableData>
}
const props = defineProps<Props>()
watch(props.tableData, (newVal, oldVal) => {
  console.log(newVal, oldVal)
})
</script>
<style></style>

其中表格的勾选列和序号列也可以添加v-if来控制隐藏

Table的类型接口和列

export interface TableOption {
  // 字段名称
  prop?: string
  // 表头
  label: string
  // 对应列的宽度
  width?: string | number
  // 对齐方式
  align?: 'left' | 'center' | 'right'
  // 自定义列模板的插槽名
  slot?: string
  // 是否是操作项
  action?: boolean
  // 是否可以编辑
  editable?: boolean
  // 属性
  attrs?: object
}
 
export interface TableData {
  date?: string
  name?: string
  address?: string
}
 
export interface FormData {
  name?: string
}
 
export const option: TableOption[] = [
  {
    label: 'Date',
    prop: 'date',
    width: 200,
    slot: 'dateSlot',
    editable: true,
    attrs: {
      sortable: ''
    }
  },
  {
    label: 'Name',
    prop: 'name',
    slot: 'nameSlot',
    attrs: {
      sortable: ''
    }
  },
  {
    label: 'Address',
    prop: 'address',
    slot: 'addressSlot',
    attrs: {
      sortable: ''
    }
  },
  {
    label: 'Edit',
    prop: 'edit',
    slot: 'editSlot'
  }
]
