[JavaScript知识库]element 表格+分页封装

原因：element ui 的表格组件默认是不带分页的功能，但是实际工作中表格总是搭配分页功能一起出现的。封装在一起使用方便不需要每次都复制粘贴一大堆。

可以根据自己的需求更改，自己根据设计图定义样式（目前是超过一页才显示分页）

<template>
  <div class="common-table-paging">
    <el-table
      v-loading="loading"
      class="common-table"
      style="width: 100%"
      :data="tableData"
      v-bind="$attrs"
      v-on="$listeners"
    >
      <template v-for="(item, index) in columns">
        <slot v-if="item.slot" :name="item.slot" />
        <el-table-column
          v-else-if="!item.children"
          :key="index"
          :type="item.type"
          :prop="item.prop"
          :sortable="item.sortable"
          :label="item.label"
          :width="item.width"
          :min-width="item.minWidth"
        />

        <el-table-column v-else :key="index" :label="item.label">
          <el-table-column
            v-for="(childItem, childIndex) in item.children"
            :key="'child' + childIndex"
            :prop="childItem.prop"
            :label="childItem.label"
            :width="childItem.width"
            :min-width="childItem.minWidth"
            :formatter="childItem.formatter"
          />
        </el-table-column>
      </template>
      <template slot="empty">
        <slot name="empty" />
      </template>
    </el-table>
    <div v-if="pagination.total > pagination.pageSize" style="height: 60px" />
    <el-pagination
      style="margin: 19px 0 0"
      class="common-pagination"
      :current-page="pagination.currentPage"
      :page-sizes="[pagination.pageSize]"
      :page-size="pagination.pageSize"
      layout="slot, prev, pager, next"
      :total="pagination.total"
      :hide-on-single-page="true"
      @current-change="handleCurrentChange"
    >
      <div v-show="totalPage > 1" class="el-pagination-jump">
        <div>第</div>
        <div class="el-pagination-editor">
          <input v-model="currentPageTemp" autocomplete="off" class="el-inpu-inner"></div>
        页/共{{ totalPage }}页
        <div
          class="jumperBtn"
          @click="jumpToPage"
        >跳转</div>
      </div>
    </el-pagination>

  </div>
</template>

<script>
export default {
  name: 'CommonTable',
  props: {
    tableData: {
      type: Array,

    loading: {
      type: Boolean,
      default: true
    },
    pagination: {
      type: Object,
      default: () => ({})
    },
    size: {
      type: String,
      default: ''
    }
  },
  data() {
    return {
      currentPageTemp: 1 // 缓存要跳转的页面
    }
  },
  computed: {
    totalPage() {
      if (this.pagination.total && this.pagination.pageSize) {
        return Math.ceil(this.pagination.total / this.pagination.pageSize)
      }
      return 0
    }
  },
  watch: {
    'pagination.currentPage': function(newVal) {
      this.currentPageTemp = newVal
    }
  },
  methods: {
    // 跳转到指定的页面
    jumpToPage() {
      if (Number(this.currentPageTemp) > this.totalPage) {
        this.currentPageTemp = this.totalPage
      }
      if (isNaN(Number(this.currentPageTemp))) {
        this.currentPageTemp = 1
      }

      this.$emit('currentPageChange', Number(this.currentPageTemp))
    },
    handleCurrentChange(val) {
      this.$emit('currentPageChange', val)

</script>

?使用：

   <CommonTable
          :table-data="tableData"
          :pagination="pagination"
          :loading="loading"
          :columns="columns"
          @currentPageChange="handleCurrentPageChange"
        >
          <el-table-column slot="type" label="测试" min-width="140">
            <template slot-scope="scope">
              <span v-if="scope.row.type === 1">已开启</span>
              <span v-else-if="scope.rowtype === 2">未开启</span>
              <span v-else>--</span>
            </template>
          </el-table-column>
          <el-table-column slot="operation" label="操作" min-width="200px">
            <template slot-scope="scope">
              <el-link

                :style="{color: '#46D9FD', marginRight: '18px'}"
                @click="handleEdit(scope.$index, scope.row,true)"
              >查看</el-link>
