在查询表格数据的时候,常常见到表格上方有一个表单区域, 用于数据查询条件动态查询表格数据.如下图:

 在此, 我开发了一个可以复用的组件. 可根据需要进行配置表单项(支持input, select, date类型的表单)和表格(支持表头配置和单元格样式配置).实现自定义配置表单个数和表格

一. 表单配置组件

表单配置组件-完整代码QueryCondition.vue

<template>
  <div style="width: 100%; height: 100%" class="form-condition">
    <div class="form-content">
      <el-form label-width="100px">
        <el-row v-for="(formType, indexs) in formTypeArray" :key="indexs">
          <el-col :span="span" v-for="(data, index) in formTypeArray[indexs]" :key="index">
            <el-form-item :label="data.label">
              <!-- 输入框类型 -->
              <el-input v-if="data.type == 'input'" v-model="formTypeArray[indexs][index].value" :placeholder="data.placeholder"></el-input>
              <!-- 时间类型 -->
              <el-date-picker popper-class="date-style" v-if="data.type == 'date'" type="date" :placeholder="data.placeholder"
                              v-model="formTypeArray[indexs][index].value"></el-date-picker>
              <!-- 下拉框类型 -->
              <el-select :popper-append-to-body="false" v-if="data.type == 'select'" v-model="formTypeArray[indexs][index].value" :placeholder="data.placeholder">
                <el-option v-for="(item, i) in data.option" :key="i" :label="item.label" :value="item.value"></el-option>
              </el-select>
            </el-form-item>
          </el-col>
          <el-col :span="span">
            <el-form-item label="">
              <div class="content-btn">
                <div class="btn-search" style="float: left" @click="getCondition">
                  <i class="el-icon-search"></i>搜索
                </div>
                <div class="btn-clean" style="float: left" @click="cleanFormValue">
                  清空
                </div>
              </div>
            </el-form-item>
          </el-col>
        </el-row>
      </el-form>
    </div>
  </div>

</template>

1. 上面的formTypeConfig变量会接收从父组件传来的数据配置表单项, 所以先从它入手

const formTypeConfig = inject("formTypeConfig");

 在父组件中配置表单信息, 必须按照这个数据格式(配置简单易懂, 不作详细说明)

父组件:

provide("formTypeConfig", [
      {label: '用户名称', type: 'input', placeholder: '请输入. . .', value: ''},
      {label: '省份', type: 'input', placeholder: '请输入. . .', value: ''},
      {label: '模式', type: 'input', placeholder: '请输入. . .', value: ''},
      {label: '行业', type: 'input', placeholder: '请输入. . .', value: ''},
      {
        label: '标签',
        type: 'select',
        placeholder: '请选择',
        option: [{label: '第一项', value: '1'}, {label: '第二项', value: '2'}],
        value: ''
      },
      {
        label: '分公司',
        type: 'select',
        placeholder: '请选择',
        option: [{label: '第一项', value: '1'}, {label: '第二项', value: '2'}],
        value: ''
      },
      {label: '受理员工号', type: 'input', placeholder: '请输入. . .', value: ''},
      {label: '流水号', type: 'date', placeholder: '请选择', value: ''},
      {label: '流水号', type: 'input', placeholder: '请输入. . .', value: ''},
      {label: '流水号', type: 'input', placeholder: '请输入. . .', value: ''},
      {label: '流水号', type: 'input', placeholder: '请输入. . .', value: ''},
      {label: '流水号', type: 'input', placeholder: '请输入. . .', value: ''},
    ]
)

在父组件中配置好数据后,表单就能根据配置自己显示出来啦~

2. 搜索和清空

搜索绑定getCondition函数, 它会把你输入到表单的数据发送给父组件, 具体的搜索操作(数据接口)请在父组件中写, 搜索出来的数据再次传给表单组件的formTypeConfig即可实现动态改变数据.

    /**
     * 给父组件返回表单输入的内容
     */
    const getCondition = () => {
      context.emit('conditionParams', formTypeArray.value)
    }
    /**
     * 清空表单内容
     */
    const cleanFormValue = () => {
      formTypeArray.value.forEach((e, index) => {
        for (let i = 0; i < e.length; i++) {
          formTypeArray.value[index][i].value = ''
        }
      })
    }

在组件中还有一个重要的方法setFormType. 他是组件的一些逻辑, 可不了解, 直接copy, 需要注意col参数, 它是配置每行显示的表单项个数, 可根据需要进行修改.

    /**
     * 设置表单类型
     * @param array 表单配置
     * @param col 每行表单项个数
     */
    function setFormType(array, col) {
      if (col == null || col == '' || array == null || array == '') {
        col = 4 // 默认分4列
      }
      span.value = 24 / col
      // 只有一行
      if (col >= array.length) {
        formTypeArray.value.push(array)
      } else {
        // 超过一行
        let deb = col
        let i = 0
        while (i < array.length) {
          let item = [] //null
          while (i < deb) {
            item.push(array[i])
            console.log(deb)
            i++
          }
          formTypeArray.value.push(item)
          if (array.length - i < col) {
            deb = array.length
          } else {
            deb = i + col
          }
        }
      }
      console.log('---------表单配置数据 SUCCESS----------');
    }

 二. 表格配置组件

TableDialog.vue

<template>
  <div class="content-table" style="width: 100%">
    <el-table :data="tableData" row-class-name="row-style" header-row-class-name="row-style">
      <!--<el-table-column type="selection" width="55"></el-table-column>-->
      <el-table-column v-for="(head, index) in tableHeader" :key="index" :label="head.label" :prop="head.fieldName"
                       :sortable="head.sortable">
        <template #default="scope">
          <div :style="scope.row[head.fieldName].style">
            {{ scope.row[head.fieldName].value }}
          </div>
        </template>
      </el-table-column>
      <el-table-column align="center" width="60px" label="操作">
        <template #default="scope">
          <div class="btn-option" @click="submitData(scope)"><i class="el-icon-tickets"></i></div>
        </template>
      </el-table-column>
    </el-table>
    <div class="pagination">
      <el-pagination
          @size-change="handleSizeChange"
          @current-change="handleCurrentChange"
          :current-page="page.currentPage"
          :page-sizes="[10, 20, 30, 40]"
          :page-size="page.size"
          layout="total, sizes, prev, pager, next"
          :total="page.total"
          popper-class='select_bottom'
      >
      </el-pagination>
    </div>
  </div>
</template>

<script>
import {inject, reactive} from "@vue/runtime-core";
import {watchEffect} from "vue";

export default {
  name: "TableDialog",
  emits: ["tableMessage"],
  setup(props, context) {
    // 数据及配置
    let tableData = reactive([])
    let page = reactive({})
    // 表头配置
 
    let tableHeader = reactive([])
    const tableHeaderConfig = inject("tableHeaderConfig");
    const tableDataConfig = inject("tableDataConfig");
    // 监听表单配置数据
    watchEffect(() => {
      console.log('-------监听tableHeaderConfig,tableDataConfig--------')
      tableHeader = tableHeaderConfig
      tableData = tableDataConfig ? tableDataConfig.tableData : []
      page = tableDataConfig ? tableDataConfig.page : {}
    })

    function submitData(scope) {
      context.emit('tableMessage', {page: page, scope: scope})
    }

    function handleSizeChange(val) {
      console.log(`每页 ${val} 条`);
      context.emit('tableMessage', {page: page, scope: null})
    }

    function handleCurrentChange(val) {
      console.log(`当前页: ${val}`);
      context.emit('tableMessage', {page: page, scope: null})
    }

    return {
      tableHeader, tableData, submitData, handleSizeChange, handleCurrentChange, page
    }
  }

和表单类似. 表格的配置也需要接收父组件传来的配置, 负责接收的参数如下:

    // 表头
    const tableHeaderConfig = inject("tableHeaderConfig");
    // 表格数据
    const tableDataConfig = inject("tableDataConfig");

数据格式如下: 

        // 设置表头 [fieldName字段名, label列名, width列宽, sortable排序]
        tableHeader.value = [
          {fieldName: 'test1', label: '客户名称', width: '250px', sortable: true},
          {fieldName: 'test4', label: '省份', width: '200px', sortable: true},
          {fieldName: 'test2', label: '客户服务模式', width: '200px', sortable: true},
          {fieldName: 'test3', label: '客户行业', width: '200px', sortable: true},
        ]
        // 表格数据
       tableDatas.value = [
      {
        number: {value: 1, style: 'color: #dfe4e9;'},
        name: {value: 'Huzz', style: 'color: #dfe4e9; font-weight: 600;'},
        sex: {
          value: 'A',
          style: 'color: #F9A400;border: 2px solid #F9A400;width: 20%;text-align: center;border-radius: 5px 5px 5px 5px;'
        },
        option: {value: '金牌', style: 'color: #FFCE57;'},
        test1: {value: '昆明', style: 'color: #dfe4e9;'},
        test2: {value: '霍咏', style: 'color: #dfe4e9;'},
        test3: {value: 18345681564, style: 'color: #dfe4e9;'}
      },
      {
