vue封装element中table组件

后台系统,table被用的次数比较多,所以决定提出来作为组件

1.新建一个Table.vue文件

<!--region 封装的分页 table-->
<template>
 <div class="table">
 <el-table id="iTable" v-loading.iTable="options.loading" :data="list" :stripe="options.stripe"
    ref="mutipleTable"
    @selection-change="handleSelectionChange">
  <!--region 选择框-->
  <el-table-column v-if="options.mutiSelect" type="selection" style="width: 55px;">
  </el-table-column>
  <!--endregion-->
  <!--region 数据列-->
  <template v-for="(column, index) in columns">
  <el-table-column :prop="column.prop"
       :key=‘column.label‘
       :label="column.label"
       :align="column.align"
       :width="column.width">
   <template slot-scope="scope">
   <template v-if="!column.render">
    <template v-if="column.formatter">
    <span v-html="column.formatter(scope.row, column)"></span>
    </template>
    <template v-else>
    <span>{{scope.row[column.prop]}}</span>
    </template>
   </template>
   <template v-else>
    <expand-dom :column="column" :row="scope.row" :render="column.render" :index="index"></expand-dom>
   </template>
   </template>
  </el-table-column>
  </template>
  <!--endregion-->
  <!--region 按钮操作组-->
  <el-table-column ref="fixedColumn" label="操作" align="center" :width="operates.width" :fixed="operates.fixed"
      v-if="operates.list.filter(_x=>_x.show === true).length > 0">
  <template slot-scope="scope">
   <div class="operate-group">
   <template v-for="(btn, key) in operates.list">
    <div class="item" v-if="btn.show" :key=‘btn.id‘>
    <el-button :type="btn.type" size="mini" :icon="btn.icon" :disabled="btn.disabled"
       :plain="btn.plain" @click.native.prevent="btn.method(key,scope.row)">{{ btn.label }}
    </el-button>
    </div>
   </template>
   </div>
  </template>
  </el-table-column>
  <!--endregion-->
 </el-table>

 </div>
</template>
<!--endregion-->
<script>
 export default {
 props: {
    list: {
      type: Array,
      default: []
      }, // 数据列表
    columns: {
      type: Array,
      default: []
      }, // 需要展示的列 === prop：列数据对应的属性，label：列名，align：对齐方式，width：列宽
    operates: {}, // 操作按钮组 === label: 文本，type :类型（primary / success / warning / danger / info / text），show：是否显示，icon：按钮图标，plain：是否朴素按钮，disabled：是否禁用，method：回调方法
    options: {
      type: Object,
      default: {
       stripe: false, // 是否为斑马纹 table
       highlightCurrentRow: false // 是否要高亮当前行
      },
    } // table 表格的控制参数
 },
//组件
 components: {
  expandDom: {
    functional: true,
    props: {
     row: Object,
     render: Function,
     index: Number,
     column: {
       type: Object,
       default: null
       }
      },
    render: (h, ctx) => {
       const params = {
       row: ctx.props.row,
       index: ctx.props.index
      }
     if (ctx.props.column) params.column = ctx.props.column
      return ctx.props.render(h, params)
    }
  }
 },
// 数据
 data () {
  return {
    pageIndex: 1,
    multipleSelection: [] // 多行选中
  }
 },
 mounted () {
 },
 computed: {
 },
 methods: {

  // 多行选中
  handleSelectionChange (val) {
    this.multipleSelection = val
    this.$emit(‘handleSelectionChange‘, val)
  },
  // 显示 表格操作弹窗
  showActionTableDialog () {
    console.log(4444)
    this.$emit(‘handelAction‘)
  }
 }
 }
</script>
<style lang="scss" >

</style>

　2.调用组件

<template>
 <div class="table-page">
 <i-table :list="list"
    @handleSelectionChange="handleSelectionChange"
    :options="options"
    :columns="columns"
    :operates="operates"
  >
 </i-table>
 </div>
</template>
<script>
 import iTable from ‘../components/Table‘
 export default {
  components: {iTable},
  data () {
   return {
    list: [
       {
        id: ‘24‘,
        title: ‘编号3‘,
        state:0
       },
       {
        id: ‘23‘,
        title: ‘编号3‘,
        state:1
       },
       {
        id: ‘23‘,
        title: ‘编号3‘,
        state:2
       },
       {
        id: ‘2‘,
        title: ‘编号3‘,
        state:0
       },
       {
        id: ‘223‘,
        title: ‘编号3‘,
        state:1
       },
       {
        id: ‘2444‘,
        title: ‘编号3‘,
        state:1
       },
    ], // table数据
    options: {
     stripe: true, // 是否为斑马纹 table
     loading: false, // 是否添加表格loading加载动画
     highlightCurrentRow: true, // 是否支持当前行高亮显示
     mutiSelect: true, // 是否支持列表项选中功能
    }, // table 的参数
    columns: [
     {
      prop: ‘id‘,
      label: ‘编号‘,
      align: ‘center‘,
     },
     {
      prop: ‘title‘,
      label: ‘标题‘,
      align: ‘center‘,
      formatter: (row, column, cellValue) => {
       return `<span style="white-space: nowrap;color: dodgerblue;">${row.title}</span>`
      }
     },
     {
      prop: ‘state‘,
      label: ‘状态‘,
      align: ‘center‘,
      render: (h, params) => {
       return h(‘el-tag‘, {
       props: {type: params.row.state === 0 ? ‘success‘ : params.row.state === 1 ? ‘info‘ : ‘danger‘} // 组件的props
       }, params.row.state === 0 ? ‘上架‘ : params.row.state === 1 ? ‘下架‘ : ‘审核中‘)
      }
     },

    ], // 需要展示的列
    operates: {
     width: 200,
     fixed: ‘right‘,
     list: [
      {
       id:‘1‘,
       label: ‘编辑‘,
       type: ‘warning‘,
       show: true,
       icon: ‘el-icon-edit‘,
       plain: true,
       disabled: false,
       method: (index, row) => {
        this.handleEdit(index, row)
       }
      },
      {
       id:‘2‘,
       label: ‘删除‘,
       type: ‘danger‘,
       icon: ‘el-icon-delete‘,
       show: true,
       plain: false,
       disabled: false,
       method: (index, row) => {
        this.handleDel(index, row)
       }
      }
     ]
    } // 列操作按钮
   }
  },
  methods: {
   // 选中行
   handleSelectionChange (val) {
    console.log(‘val:‘, val)
   },
   // 编辑
   handleEdit (index, row) {
    console.log(‘ index:‘, index)
    console.log(‘ row:‘, row)
   },
   // 删除
   handleDel (index, row) {
    console.log(‘ index:‘, index)
    console.log(‘ row:‘, row)
   }
  }
 }
</script>
