Vue3+Element Plus实现el-table跨行显示

app组件内容
- 使用:span-method="objectSpanMethod"自定义方法实现跨行显示
- 查询方法
- 初始化挂载
- 新建一个html即可进行测试，完整代码如下
- 效果图

app组件内容

 <div id="app"><!-- 远程搜索 --><el-form :inline="true" :model="formInline" class="demo-form-inline"><el-form-item label="任务名称：" style="margin-left:30px;"><el-select v-model="value" filterable remote clearable reserve-keyword placeholder="Please enter a keyword" :remote-method="remoteMethod" :loading="loading"><el-option v-for="item in options" :key="item.CODE" :label="item.NAME" :value="item.CODE" /></el-select></el-form-item><el-form-item><el-button type="primary" @click="onSubmit">查询</el-button></el-form-item></el-form><!-- 表格数据 --><el-table :data="tableData" stripe border style="width: 98%;" :span-method="objectSpanMethod" max-height="650"><el-table-column fixed prop="CODE" label="编码" width="60"></el-table-column><el-table-column prop="NAME" label="名称"></el-table-column><el-table-column prop="FREQUENCY" label="频次" width="80"></el-table-column><el-table-column prop="FNAME" label="执行科室" width="150"></el-table-column><el-table-column prop="FILENAME" label="文件名称"></el-table-column><el-table-column prop="STATUS" label="状态" width="80"></el-table-column><el-table-column prop="CREATEID" label="上传人" width="80"></el-table-column><el-table-column prop="CREATEDATE" label="上传时间"></el-table-column></el-table></div>

使用:span-method="objectSpanMethod"自定义方法实现跨行显示

const objectSpanMethod = ({row,column,rowIndex,columnIndex}) => {const columnsToSpan = ['CODE', 'NAME', 'FNAME', 'FREQUENCY']; // 列名数组if (columnsToSpan.includes(column.property)) {if (rowIndex === 0 || row[column.property] !== tableData.value[rowIndex - 1][column.property]) {// 如果是相同 "NAME" 的第一行，则返回正确的 rowspan 和 colspanlet rowspan = 1;for (let i = rowIndex + 1; i < tableData.value.length; i++) {if (tableData.value[i][column.property] === row[column.property]) {rowspan++;tableData.value[i]._rowspan = 0; // 隐藏后续行的 "NAME"} else {break;}}return {rowspan,colspan: 1};}return {rowspan: 0,colspan: 0}; // 隐藏相同 "NAME" 的后续行}return {rowspan: 1,colspan: 1};}

查询方法

const onSubmit = (boolen) => {// 在这里获取输入的值const inputValue = value.value;if ((inputValue !== null && inputValue !== undefined && inputValue !== '') || boolen) {// console.log("Input Value:", inputValue);// axios.get(UJCAjaxBaseUrl + "/请求地址", {//     params: {//         TaskId: inputValue//     }// }).then((response) => {//     console.log("response:" + response.data.data);//     tableData.value = response.data.data;//     return true;// }).catch((error) => {//     console.error('发生错误：', error);//     return false;// });} else {showErrorMessage('请搜索并选择您要查询的细则编码或细则名称!');return false;}

初始化挂载

  //初始化挂载onMounted(() => {list.value = states.map((item) => {return {value: item};});onSubmit(true);});

新建一个html即可进行测试，完整代码如下
