表格首列相同數據合并

1. 添加文件

1.src/views 下新建mergeCell.vue文件，代碼如下：

<template>
  <div id="app">
    <el-table
            :data="tableData"
            :span-method="(param)=>objectSpanMethod(param)"
            >
            <el-table-column
                prop="type_test"
                label="類型"               
                align='center'>
            </el-table-column>
            <el-table-column
                prop="type_spec"
                label="模塊"
                align='center'
                >
            </el-table-column>
            <el-table-column
                prop="is_execute"
                label="是否執行"
                align='center'
               >
                <template slot-scope="scope">
                    <span v-if="scope.row.is_execute == true">已執行</span>
                    <span v-if="scope.row.is_execute == false">未執行</span>
                </template>
            </el-table-column>
            <el-table-column
                prop="result_status"
                label="結果"
                align='center'
               >
                <template slot-scope='scope'>
                    <el-tag :type="scope.row.result_status | ResultFilter">
                        {{scope.row.result_status}}
                    </el-tag>
                </template>
            </el-table-column>
            <el-table-column
                prop="created_at"
                label="創建時間"
                align='center'
               >
                <template slot-scope="scope">
                {{ scope.row.created_at}}
            </template>
            </el-table-column>
        </el-table>
  </div>
</template>
<script>

export default {
    filters:{
        ResultFilter(status) {
        const ongSteadyMap = {
            SUCCESS: 'success',
            FAILURE: 'danger',
            NA: 'primary',
            ABORTED:'info',
            FAIL:'danger',
            None: 'warning'
      }
      return ongSteadyMap[status]
    },
      },
    data() {
        return {
            tableData:[
                {
                    "id": 1,
                    "created_at": "2023-06-18 11:51:07",
                    "updated_at": "2023-04-18 11:51:07",
                    "type_test": "功能測試",
                    "type_spec": "登錄",
                    "is_execute": true,
                    "result_status": "SUCCESS"
                },
                {
                    "id": 2,
                    "created_at": "2023-06-18 11:51:07",
                    "updated_at": "2023-06-18 11:51:07",
                    "type_test": "功能測試",
                    "type_spec": "退出",
                    "cr_id": "",
                    "is_execute": true,
                    "result_status": "SUCCESS"
                },
                {
                    "id": 3,
                    "created_at": "2023-06-18 11:51:07",
                    "updated_at": "2023-06-18 11:51:07",
                    "type_test": "接口測試",
                    "type_spec": "登錄",
                    "cr_id": "",
                    "is_execute": false,
                    "result_status": "N/A"
                },
                {
                    "id": 4,
                    "created_at": "2023-06-18 11:51:07",
                    "updated_at": "2023-06-18 11:51:07",
                    "type_test": "接口測試",
                    "type_spec": "退出",
                    "cr_id": "",
                    "is_execute": true,
                    "result_status": "FAIL"
                }
            ]
        };
    },
    methods: {
        objectSpanMethod({ row, column, rowIndex, columnIndex }) {
            console.log('objectSpanMethod',row, column, rowIndex, columnIndex)
            if (columnIndex === 0) {
                    const _row = this.flitterData(this.tableData).one[rowIndex];
                    const _col = _row > 0 ? 1 : 0;
                    return {
                        rowspan: _row,
                        colspan: _col,
                    };
		    }
        },
        flitterData(arr) {
            // 合并表格第一列
            let spanOneArr = [];
            let concatOne = 0;
            arr.forEach((item, index) => {

                if (index === 0) {
                    spanOneArr.push(1);
                    }
                else {
                    console.log('item',item,index)
                    console.log('arr',arr[index-1])
                    // 這里的type_test是表格綁定的字段，也就是需要合并的字段，根據自己的需求來改
                    if (item.type_test == arr[index -1].type_test) {
                        // 第一列需合并相同內容的判斷條件
                        spanOneArr[concatOne] += 1;
                        spanOneArr.push(0);
                    } else {
                        spanOneArr.push(1);
                        concatOne = index;
                    }

                }
            });
            return {
                one: spanOneArr,
            };
        },
        
    }
};
</script>

2. 添加路徑

在router下添加，如下路徑

{
    path: '/mergeCell',
    component: Layout,
    children: [
      {
        path: 'mergeCell',
        name: 'mergeCell',
        component: () => import('@/views/mergeCell.vue'),
        meta: { title: 'mergeCell', icon: 'form' }
      }
    ]
  },

3. 查看效果

npm run dev 運行，效果如下圖
