合并Element ui单元格

这个方法是处理后台拿过来的数据

getSpanArr(data) {// data就是我们从后台拿到的数据this.spanArr = [];let that = this;setTimeout(function () {// console.log(data.length);for (var i = 0; i < data.length; i++) {// console.log(data[i].category_id);if (i === 0) {that.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].category_id === data[i - 1].category_id) {that.spanArr[this.pos] += 1;that.spanArr.push(0);} else {that.spanArr.push(1);this.pos = i;}}}console.log(that.spanArr);}, 200);},

 前端更改数据，更改为需要的数据，我这是添加数据

addrow(a, b) {//  numa = numaconst loading = this.$loading({target: document.querySelector("#table"), //loadin覆盖的dom元素节点});console.log(a, b);let obg = {id: "",name: b.name,category_id: b.category_id,namea: "",space: [],type: 0,isshow: true,isshowa: false,inpua: "",inpub: "",};//添加单元格到最后let subscript = this.datab.filter((item) => {return item.name == obg.name;});let subscript1 = this.datab.findIndex((item) => {return item.name == obg.name;});// console.log(subscript.length, subscript1);this.datab.splice(subscript1 + subscript.length, 0, obg);console.log(this.datab);this.getSpanArr(this.datab);setTimeout(() => {loading.close();}, 600);},

合并单元格时用到处理过的数据

  objectSpanMethod({ row, column, rowIndex, columnIndex }) {if (columnIndex === 0) {const _row = this.spanArr[rowIndex];const _col = _row > 0 ? 1 : 0;// console.log(`rowspan:${_row} colspan:${_col}`);return {// [0,0] 表示这一行不显示， [2,1]表示行的合并数rowspan: _row,colspan: _col,};}},
