1、el-table 上绑定方法 :span-method="objectSpanMethod"
// 表格合并行
objectSpanMethod ({ row, column, rowIndex, columnIndex }) {
if (columnIndex === 1) {
const _row = this.testArr1[rowIndex];
const _col = _row > 0 ? 1 : 0;
// console.log(_col,'hhhh')
return {
rowspan: _row,
colspan: _col,
};
}
if (columnIndex === 2) {
const _row = this.testArr2[rowIndex];
const _col = _row > 0 ? 1 : 0;
return {
rowspan: _row,
colspan: _col,
};
}
if (columnIndex === 0) {
const _row = this.testArr3[rowIndex];
const _col = _row > 0 ? 1 : 0;
return {
rowspan: _row,
colspan: _col,
};
}
},
2、 rowspan (spanArr, position, spanName) {
this.tableData.forEach((item, index) => {
if (index === 0) {
spanArr.push(1);
position = 0;
} else {
// console.log(this.tableData[index][spanName])
if (
this.tableData[index][spanName] ===
this.tableData[index - 1][spanName]
) {
if (this.tableData[index][spanName]) {
spanArr[position] += 1;
spanArr.push(0);
} else {
spanArr.push(1);
position = index;
}
} else {
spanArr.push(1);
position = index;
}
}
});
},
2、在获取表格数据的请求里面（记得先清空数据、不然加载有问题）
this.testArr1 = []
this.testArr2 = []
this.testArr3 = []
this.rowspan(this.testArr1, this.testPosition1, "sxmc");
this.rowspan(this.testArr2, this.testPosition2, "sxyq");
this.rowspan(this.testArr3, this.testPosition3, "index");
