如果对第二列进行合并的话copy一下第一个方法，让值赋给第二个数组就可以

 // 合并方法mergeCells({ row, column , rowIndex, columnIndex }) {debugger;if (columnIndex === 1) {const _row = this.spanArr[rowIndex];const _col = _row > 0 ? 1 : 0;console.log(_col, '_col');return {rowspan: _row, //行colspan: _col //列};}else if (columnIndex ===2){const _row = this.spanSecondArr[rowIndex];const _col = _row > 0 ? 1 : 0;console.log(_col, '_col');return {rowspan: _row, //行colspan: _col //列};}},getSpanFirstArr(data) {this.spanArr = [];for (var i = 0; i < data.length; i++) {if (i === 0) {this.spanArr.push(1);this.pos = 0;} else {// 判断当前元素与上一个元素是否相同if (data[i].orgName === data[i - 1].orgName && data[i].orgName) {this.spanArr[this.pos] += 1;this.spanArr.push(0);} else {this.spanArr.push(1);this.pos = i;}}}},// 对类型的合并getSpanSecondArr(data) {this.spanSecondArr = [];for (var i = 0; i < data.length; i++) {if (i === 0) {this.spanSecondArr.push(1);this.pos = 0;} else {// 判断当前元素与上一个元素是否相同if (data[i].wgareaType === data[i - 1].wgareaType && data[i].wgareaType) {this.spanSecondArr[this.pos] += 1;this.spanSecondArr.push(0);} else {this.spanSecondArr.push(1);this.pos = i;}}}},```
