获取当前数组的下标使用 

scope.$index ：获取当前行的下标
scope.row：获取当前行的对象              然后使用v-for遍历，

v-for="(item, index) in invoice[scope.$index].invoices"

合并列

     //合并列
      arraySpanMethod({ row, column, rowIndex, columnIndex }) {
          if (columnIndex === 3) {
            return [1, 7];
          }else if (columnIndex === 9){
            return [1,1];
          }
      }

通过给table传入span-method方法可以实现合并行或列，方法的参数是一个对象，里面包含当前行row、当前列column、当前行号rowIndex、当前列号columnIndex四个属性。该函数可以返回一个包含两个元素的数组，第一个元素代表rowspan，第二个元素代表colspan。 也可以返回一个键名为rowspan和colspan的对象。
