一 --- 表格合并

1. 需求页面如下:

这个需求如果直接用 js 写的话就太简单了.但是使用 vue, 就需要自己修改了. 其实也不是很难,主要还是数据解析

2. 数据结构如下:

 var list = [
        {
          "id": "16EE8A54E6917F6479905CDC5B031F22",
          "activityPointsDOS": [

      ];

3. 代码如下:

二 --- 表格纵向表头

官网上的案例都是横向的表格, 如下图:

而经常会遇到的需求就是纵向的表头. 数据结构不同, 写法也不一样, 各取所需.

1. 需求页面如下:

2. 数据结构如下:

补充说明: list 中的 id 是学生的日志 id, 如果 id 为 0 说明当天日志没有完成,将显示未完成, 如果有将显示可查看

loginfo: {
      'students': [
              {
                 'id':1,
                 'name':'张三',
                 'list': [
                      {'id':11},
                      {'id':0},
                      {'id':0},
                      {'id':0}]
              },
              {
                  'id':2,
                  'name':'李四',
                  'list': [
                      {'id':'21'},
                      {'id':0},
                      {'id':0},
                      {'id':0}]
              },
              {
                  'id':3,
                  'name':'王二麻子',
                  'list': [
                      {'id':0},
                      {'id':0},
                      {'id':0},
                      {'id':36}]
              },
      'dateList': ['06-01','06-02','06-03','06-04']
}

3. 代码如下:

        <el-table
            :data="loginfo.students"
            border
            style="width: 100%">
            <el-table-column
              prop="name"
              width="150"
              align="center"
              label="姓名/日期"
              fixed
            >
            </el-table-column>
            <template v-for='(col,i) in loginfo.dateList'>
              <el-table-column
                :show-overflow-tooltip="true"
                :label="col"
                :key="col"
                width="100"
                align="center"
              >
                <template slot-scope="scope">
                  <span>
                  <el-tag @click="showLog(scope.row, i)"
                          :type="scope.row.list[i].id != 0 ? 'success' : 'danger'"> {{scope.row.list[i].id != 0 ? '可查看' : '未完成'}}</el-tag>
                </span>
                </template>
              </el-table-column>
            </template>
          </el-table>
