Excel formula 如果A在B中有匹配项，则将与B相关的值添加到C中

我有三个专栏

A=日历年中每天的列表：

January 1, 2018
January 2, 2018
etc.

B=某事件发生年份的某些日期列表

January 5, 2018
January 12, 2018
February 1, 2018
March 12, 2018
etc.

C=与B列中事件日期相关的时间值

我想简单地应用C中的值来关联A列中的正确日期，并将值放入D列

现在没有D列的情况下是这样的，我希望D列如下所示。我希望将时间值应用到与A列中的日期对应的右侧行。我只是尝试显示贯穿全年的数据，而不是在没有像B列和C列中当前那样的事件时跳过日期

您需要在D列中使用VLOOKUP语句

以下是一个例子：

=IFERROR(VLOOKUP(A1,B$1:C$365,2,FALSE),0)

IFERROR声明，如果您没有该日期的条目，它将显示0，而不是显示错误

A1单元格是此D1单元格的相关日期。B1:C365是我们的查找表，它查看每个B单元以查找与此行相关的时间条目。2表示我们希望VLOOKUP返回数组的第二列，即C列。如果将公式粘贴到不同的单元格中，$s可以防止数组的列号发生变化

FALSE强制VLOOKUP查找精确匹配，否则将使用近似匹配。

尝试索引+匹配

在单元格D1中输入上述内容并将其向下拖动

最好用精确的范围替换C:C和B:B，而不是引用整个列。确保在使用精确范围时，这两个范围必须相互匹配，例如C1:C100与B1:B100，但不包括C2:C100与B1:B101

使用VLOOKUP公式=VLOOKUPA1，B:C，2，错

=IFERROR(INDEX(C:C,MATCH(A1,B:B,0)),0)
