vue表格合并行的一个实例

    一、element控件实现

      在平常的应用中,需要用到合并单元格的操作,在Excel中,这种操作很好实现,但在实际项目中,常常需要借助element控件来实现。

      下面是element中的一个实例:

      

实现的代码如下:

<template>
  <div>
    <el-table
      :data="tableData"
      :span-method="arraySpanMethod"
      border
      style="width: 100%">
      <el-table-column
        prop="id"
        label="ID"
        width="180">
      </el-table-column>
      <el-table-column
        prop="name"
        label="姓名">
      </el-table-column>
      <el-table-column
        prop="amount1"
        sortable
        label="数值 1">
      </el-table-column>
      <el-table-column
        prop="amount2"
        sortable
        label="数值 2">
      </el-table-column>
      <el-table-column
        prop="amount3"
        sortable
        label="数值 3">
      </el-table-column>
    </el-table>

    <el-table
      :data="tableData"
      :span-method="objectSpanMethod"
      border
      style="width: 100%; margin-top: 20px">
      <el-table-column
        prop="id"
        label="ID"
        width="180">
      </el-table-column>
      <el-table-column
        prop="name"
        label="姓名">
      </el-table-column>
      <el-table-column
        prop="amount1"
        label="数值 1(元)">
      </el-table-column>
      <el-table-column
        prop="amount2"
        label="数值 2(元)">
      </el-table-column>
      <el-table-column
        prop="amount3"
        label="数值 3(元)">
      </el-table-column>
    </el-table>
  </div>
</template>

<script>
  export default {
    data() {
      return {
        tableData: [{
          id: '12987122',
          name: '王小虎',
          amount1: '234',
          amount2: '3.2',
          amount3: 10
        }, {
          id: '12987123',
          name: '王小虎',
          amount1: '165',
          amount2: '4.43',
          amount3: 12
        }, {
          id: '12987124',
          name: '王小虎',
          amount1: '324',
          amount2: '1.9',
          amount3: 9
        }, {
          id: '12987125',
          name: '王小虎',
          amount1: '621',
          amount2: '2.2',
          amount3: 17
        }, {
          id: '12987126',
          name: '王小虎',
          amount1: '539',
          amount2: '4.1',
          amount3: 15
        }]
      };
    },
    methods: {
      arraySpanMethod({ row, column, rowIndex, columnIndex }) {
        if (rowIndex % 2 === 0) {
          if (columnIndex === 0) {
            return [1, 2];
          } else if (columnIndex === 1) {
            return [0, 0];
          }
        }
      },

      objectSpanMethod({ row, column, rowIndex, columnIndex }) {
        if (columnIndex === 0) {
          if (rowIndex % 2 === 0) {
            return {
              rowspan: 2,
              colspan: 1
            };
          } else {
            return {
              rowspan: 0,
              colspan: 0
            };
          }
        }
      }
    }
  };
</script>

     二、原生方法实现

但是,这种局限性很大,要是需要合并的单元格和实例中的不匹配,那就不行了。比如说实际需求是下面的这种形式的表格:

开始用element控件发现实现不了,然后最后用原生方法实现的,关键代码如下:

 <table>
      <thead>
        <th>数据类型</th>
        <th>名称</th>
        <th></th>
        <th></th>
      </thead>
      <tbody>
        <template v-for="(item,index) in tableData">
          <tr :key="index">
            <td :rowspan="item.rowSpanData.length">{{item.rowSpanName}}</td>
            <td >{{item.rowSpanData[0].value01}}</td>
            <td >{{item.rowSpanData[0].value02}}</td>
            <td >{{item.rowSpanData[0].value03}}</td>
          </tr>
          <tr v-for="(ele,inx) in item.rowSpanData.length-1" :key="index+'-'+inx">
            <td>{{item.rowSpanData[ele].value01}}</td>
            <td>{{item.rowSpanData[ele].value02}}</td>
            <td>{{item.rowSpanData[ele].value03}}</td>
          </tr>
        </template>
      </tbody>
    </table>

  

 tableData: [
        {
          rowSpanName: "基础数据",
          rowSpanData: [
            {
              value01: "钻井层位()",
              value02: "",
              value03: ""
            },
            {
              value01: "上层套管尺寸(in)",
              value02: "",
              value03: "" 
            },
            {
              value01: "上层套管下深(m)",
              value02: "",
              value03: ""
            },
             {
              value01: "本层钻头尺寸(in)",
              value02: "7.5",
              value03: ""
            },
             {
              value01: "本层井深(m)",
              value02: "5950",
              value03: ""
            },
             {
              value01: "本层井底部垂深(m)",
              value02: "",
              value03: ""
            },
             {
              value01: "本层套管尺寸(in)",
              value02: "4",
              value03: ""
            },
           {
              value01: "本层套管下深(m)",
              value02: "5948.6",
              value03: ""
            },
           {
              value01: "浮箍下深(m)",
              value02: "5928.6",
              value03: ""
            },
           {
              value01: "球座/阻流环下深(m)",
              value02: "5928.6",
              value03: ""
            },
           {
              value01: "分级箍顶深(m)",
              value02: "",
              value03: ""
            },
           {
              value01: "尾管挂顶深(m)",
              value02: "3050",
              value03: ""
            },
          ]
        },
        {
          rowSpanName: "地质分层",
          rowSpanData: [
            {
              value01: "层位()",
              value02: "",
              value03: ""
            },
            {
              value01: "底深(m)",
              value02: "",
              value03: ""
            },
            {
              value01: "主要岩性描述()",
              value02: "",
              value03: ""
            }
          ]
        },
        {
          rowSpanName: "其他",
          rowSpanData: [
            {
              value01: "目的层1顶深(m)",
              value02: "",
              value03: ""
            },
            {
              value01: "目的层1顶深TVD(m)",
              value02: "",
              value03: ""
            }
          ]
        }
      ],
<style scoped>
table {
  width: 600px;
  border: 1px solid #ccc;
  border-collapse: collapse;
}
thead th{
    text-align: left;
    background-color: #fafafa;
}
th,td {
  padding-left: 20px;
  border: 1px solid #e9eaec;
  line-height: 30px;
}
</style>

实现的效果如下:

 

以上就是实际需求中的一个例子,element控件应该也能实现第二种多行合并的表格,后面可以深入研究一下。
