我想把句子里的单词整理成这几行，然后按会员ID排序

member-0 sanders1 group1 1
member-1 sanders2 group1 1
member-2 sanders3 group1 1
member-3 sanders4 group1 1
member-4 Matty1 group0 1
member-5 Kendal1 group2 2
member-6 colen1 group3 2
member-7 colen2 group3 2
member-8 colen3 group3 2
member-14 Matty2 group0 1
member-15 Kendal2 group2 2

我有下面这张表，如何计算仅 11 月记录的字节总和？例如下面我想在 11 月找到行，然后将第 4 列中与 11 月相关的数字相加？我该怎么做？
