excel：查找每个组的最大日期的total_log

Question

我喜欢一个sheet1，它将在eveyday更新：

+---------+----------+-----------+
| company |   date   | total_log |
+---------+----------+-----------+
| A       | 20180910 |     32987 |
| A       | 20180902 |       426 |
| A       | 20180905 |     42135 |
| B       | 20180906 |     64743 |
| B       | 20180910 |    235647 |
| B       | 20180902 |      2346 |
| C       | 20180804 |     67536 |
| C       | 20180910 |     34536 |
| C       | 20180510 |    235356 |
+---------+----------+-----------+

如何通过Excel自动基于Sheet1更新Sheet2上的日期和total_log列，并使用Excel自动为每个公司提供最大日期

+---------+------+-----------+
| company | date | total_log |
+---------+------+-----------+
| A       |      |           |
| B       |      |           |
| C       |      |           |
+---------+------+-----------+

Sheet2 B2的公式

=MAX(INDIRECT(ADDRESS(IF($A1="company",1,MATCH($A1,Sheet1!$A$1:$A$11)), 2, 1,1, "Sheet1")&":"&ADDRESS(MATCH($A2,Sheet1!$A$1:$A$11), 2, 1, 1)))

Sheet2 B3的公式

=MAX(INDIRECT(ADDRESS(IF($A1="company",1,MATCH($A1,Sheet1!$A$1:$A$11)), 3, 1,1, "Sheet1")&":"&ADDRESS(MATCH($A2,Sheet1!$A$1:$A$11), 3, 1, 1)))
