< template > < el-container > < el-main > < el-table :data = "tableData" border style = "width: 100%" :span-method = "objectSpanMethod" //添加这个实现行数据合并 > < el-table-column label = "序号" prop = "id" align = "center" ></ el-table-column > < el-table-column label = "名字" prop = "screenName" align = "center" ></ el-table-column > < el-table-column label = "时间1" prop = "startTime" align = "center" ></ el-table-column > < el-table-column label = "时间2" prop = "endTime" align = "center" ></ el-table-column > </ el-table > </ el-main > </ el-container > </ template > < script > export default { name: "Formtableyes", data() { return { //合并行 spanArr: [], //声明一个数组 tableData: [ { id: 1, screenName: "LHC", startTime: "12", endTime: "1231" }, { id: 1, screenName: "LHC", startTime: "12", endTime: "123" } ] }; }, mounted: function() { this.tableDatas(); //加载数据就调用该方法 }, methods: { objectSpanMethod({ row, column, rowIndex, columnIndex }) { if (columnIndex === 0) { //合并第一列 const _row = this.spanArr[rowIndex]; const _col = _row > 0 ? 1 : 0; return { rowspan: _row, colspan: _col }; } if (columnIndex === 1) { //合并第二列 const _row = this.spanArr[rowIndex]; const _col = _row > 0 ? 1 : 0; return { rowspan: _row, colspan: _col }; } // if (columnIndex === 2) { //合并第三列 // const _row = this.spanArr[rowIndex]; // const _col = _row > 0 ? 1 : 0; // return { // rowspan: _row, // colspan: _col // }; // } }, tableDatas() { let contactDot = 0; this.tableData.forEach((item, index) => { item.index = index; if (index === 0) { this.spanArr.push(1); } else { if (item.id === this.tableData[index - 1].id) { this.spanArr[contactDot] += 1; this.spanArr.push(0); } else { this.spanArr.push(1); contactDot = index; } } }); }, } }; </ script > < style scoped> .ptselect { width: 100%; } </ style > |
效果如下:
