数据未排序时（需要合并的行数据未处于相邻位置）

// 排序方法
groupByKeys(keyLis) {let list = this.tableData;let res = list.sort((a, b) => {// localeCompare汉字排序const sor1 = b[keyLis[0]].localeCompare(a[keyLis[0]], 'zh');if (sor1 !== 0) return sor1;return a[keyLis[1]].localeCompare(b[keyLis[1]], 'zh');});this.tableData = res;
}

固定合并行（写死）

changeSpanMethod({row,column,rowIndex,columnIndex
}) {if (columnIndex === 0) {if (rowIndex === 0) {return {rowspan: 11,colspan: 1};} else {return {rowspan: 0,colspan: 0};}}if (columnIndex === 1) {if (rowIndex === 0) {return {rowspan: 8,colspan: 1};} else if (rowIndex === 8) {return {rowspan: 3,colspan: 1};} else {return {rowspan: 0,colspan: 0};}}if (columnIndex === 2) {if (rowIndex === 0) {return {rowspan: 8,colspan: 1};} else if (rowIndex === 8) {return {rowspan: 3,colspan: 1};} else {return {rowspan: 0,colspan: 0};}}if (columnIndex === 3) {if (rowIndex === 0) {return {rowspan: 8,colspan: 1};} else if (rowIndex === 8) {return {rowspan: 3,colspan: 1};} else {return {rowspan: 0,colspan: 0};}}if (columnIndex === 4) {if (rowIndex === 0) {return {rowspan: 1,colspan: 1};} else if (rowIndex === 1) {return {rowspan: 7,colspan: 1};} else if (rowIndex >= 2 && rowIndex <= 7) {return {rowspan: 0,colspan: 0};} else {return {rowspan: 1,colspan: 1};}}
}

动态合并行

// 合并行数计算
calculateSpans() {const spanConfig = this.spanConfig;const tempMap = new Map();spanConfig.forEach(prop => {const spans = [];let position = 0;this.tableData.forEach((item, index) => {if (index === 0) {spans.push(1);position = 0;} else {// 当前行内容与上一行相同if (this.tableData[index][prop] === this.tableData[index - 1][prop]) {spans[position] += 1;spans.push(0);} else {spans.push(1);position = index;}}});tempMap.set(prop, spans);});this.spanMap = tempMap;
}

方法（函数）执行

// 注：一下两个方法执行顺序不能颠倒
// 排序方法执行（如果不需要排序，那就不用执行排序方法）
this.groupByKeys(['name', 'amount3']);
// 计算合并行方法执行
this.calculateSpans();
