table标签一行三列，行的宽度为100%，左边两列为固定宽度，要求右边宽度为百分比。

Posted 2023-04-24

<table style="width:100%;">
<tr>
<td style="width:30px;">1</td><td style="width:50px;">2</td><td>3</td>
</tr>
</table>

table的宽度为100%，左边两列固定宽度，table自然会给剩下的那一列表格的剩余宽度。 参考技术A 要么都用固定宽度,要么最后一个单元格不设置宽度,要么都使用百分比.如果你第三个单元格指定的宽度与前两个之和不等于100%,那还不如不指定,可能引起混乱.

elementui组件table表，同时合并列合并行的解决办法

 

项目需要实现每三行合并两行，然后每三行合并三列，下图这种效果：

代码：

<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>

vue部分：

var Main = {
    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
        }, {
          id: \'12987126\',
          name: \'王小虎\',
          amount1: \'666\',
          amount2: \'4.1\',
          amount3: 15
        }, {
          id: \'12987126\',
          name: \'王小虎\',
          amount1: \'777\',
          amount2: \'4.1\',
          amount3: 15
        }, {
          id: \'12987126\',
          name: \'王小虎\',
          amount1: \'888\',
          amount2: \'4.1\',
          amount3: 15
        }, {
          id: \'12987126\',
          name: \'王小虎\',
          amount1: \'999\',
          amount2: \'4.1\',
          amount3: 15
        }]
      };
    },
    methods: {
      arraySpanMethod({ row, column, rowIndex, columnIndex }) {
        if(columnIndex === 0) {
　　　　　　//每三行，合并两行
          if ((rowIndex+1) % 3 === 1) {
            return {
              rowspan: 2,
              colspan: 1
            };
          }else if ((rowIndex+1) % 3 === 0 ) { //每三行合并三列 
            return [1, 3];
          }
        }
      }
    }
  };
var Ctor = Vue.extend(Main)
new Ctor().$mount(\'#app\')
