1.需要实现的效果
use-span-method.js文件
* 合并相同数据，导出合并列所需的方法(只适合el-table)
* @param {Object} data
* @param {Object} rowSpanArray
*/
export function getRowSpanMethod(data, rowSpanArray) {

* 要合并列的数据
*/

//初始化 rowSpanNumObject
rowSpanArray.map(item => {

});
//计算相关的合并信息
for (let i = 1; i < data.length; i++) {

if (data[i][key] === data[i - 1][key]) {

});

// console.log(rowSpanNumObject)
//提供合并的方法并导出
// row columnIndex
const spanMethod = function({ column, rowIndex }) {
