vue+elementUI实现表格组件的封装

效果图：

在父组件使用表格组件

<table-list
          ref="table"
          :stripe="true"
          :loading="loading"
          :set-table-h="slotProps.setMainCardBodyH"
          :table-data="tableData"
          :columns="columns.tableList || []"
          :radio="topicTypeListMapItem.radio"
          show-opear
          show-selection
          :fix-width="240"
          :page-data="pageData"
          :disabled-select-key="topicTypeListMapItem.disabledSelectKey"
          @changeSize="changeSize"
          @changePage="changePage"
        >
          <!--预警灯-->
          <template #warningLight="{ row }">
            <div class="lightCireBlock">
              <div>
                <div v-for="(item,index) in row.warningLight" :key="'warningLight'+index">
                  <svg-icon v-if="Object.keys(columns.warningLight).includes(item)" :icon-class="columns.warningLight[item].icon" class="task-icon" />
                  <span
                    v-if="columns.warningLight[item] && columns.warningLight[item].hasNum && row[`warningLight${item}`] * 1 > 0"
                    class="fontBoxAll fontBox"
                  >{{ row[`warningLight${item}`] }}</span>
                </div>
              </div>
            </div>
          </template>
          <!--标题-->
          <template #taskTitle="{ row }">
            <span class="td-cell lineCell" @click="editMainEvent(row)"> {{ row.taskTitle }}</span>
          </template>
          <!--状态-->
          <template #status="{ row }">
            <el-tag :disable-transitions="true" :class="columns.statusLists[row.status].className">{{ columns.statusLists[row.status].label }}</el-tag>
          </template>
          <!--操作-->
          <template slot-scope="{ row }">
            <div class="table-buttonList">
              <template v-for="(item,index) in columns.btnList">
                <el-button
                  v-if="item.isShow?item.isShow(row):true"
                  :key="index"
                  type="text"
                  @click="btnFn[item.clickFn.fn](row,...(item.clickFn.params?item.clickFn.params:[]))"
                >{{ item.name }}</el-button>
              </template>
            </div>
          </template>
        </table-list>

然后用一个js文件来存储动态的参数

import { selectOverseerMeetingLeaType } from '@/api/common.js'

export const topicTypeListMap = new Map([
  [
    'keyWork',
    {
      name: '重点工作',
      radio: false, // 表格数据是否单选
      showImportBtn: true, // 是否显示批量导入按钮
      showApprovalBtn: false, // 是否显示送立项按钮
      showImportApprovalBtn: false, // 导入时是否显示送立项按钮
      showItemTypeBtn: false, // 导入时是否显示选择事项类型按钮
      showWorkRequireBtn: false, // 导入时是否显示批量填写工作要求按钮
      showFoliCureBtn: false, // 是否显示送办理按钮
      hasSubtasks: true, // 专题是否有子任务
      isMeetingTopicType: false, // 是否是会议类专题
      disabledSelectKey: [{ label: 'status', value: '0' }, { label: 'status', value: '1' }] // 表格哪些状态的数据禁选
    }
  ],
  [
    'feasibleInstructions',
    {
      name: '督办件',
      radio: false,
      showImportBtn: true,
      showApprovalBtn: true,
      showImportApprovalBtn: true, // 导入时是否显示送立项按钮
      showItemTypeBtn: true, // 导入时是否显示选择事项类型按钮
      showWorkRequireBtn: false, // 导入时是否显示批量填写工作要求按钮
      showFoliCureBtn: true,
      hasSubtasks: false,
      isMeetingTopicType: false,
      disabledSelectKey: []
    }
  ]

])

在组件中

          rows: 15,
          pageSize: [15, 25, 35],
          total: 0
        }
      }
    },
    isImportData: { // 判断是否导入的数据
      type: Boolean,
      default: false
    },
    disabledSelectKey: { // 需要禁用的选择框的数据
