根据下拉选择将文本附加到单元格值

Posted 2021-05-04

我有一个公式来组合几个值：

1. C栏中的值
2. 如果有空格，请添加“和”
3. 下拉列I中的选择值
4. 根据第I列中的下拉选择分配的值（例如B1，​​C1）
5. 将B1或C1附加到C列中的值，结果显示在M列中

M栏中的公式：

=IF(I15="Truck",CLEAN(SUBSTITUTE(SUBSTITUTE(TRIM(C15),"and ","And"),CHAR(32),"")),IF(I15="Bus",CLEAN(SUBSTITUTE(SUBSTITUTE(TRIM(C15),"and","And"),CHAR(32),"")& "B1"),IF(I15="Car",CLEAN(SUBSTITUTE(SUBSTITUTE(TRIM(C15),"and","And"),CHAR(32),"")),"")& "C1"))

除了一小部分外，它有效;只要C列中的值为空白，默认情况下会将C1填充到M列中。 M列中的值应为空白。

有什么想法吗？

答案

真正的问题是当I15空白时。运行“评估公式”工具，您应该看到它，但是如果您破坏了代码并使用缩进/新行等格式化它：

=IF(I15="Truck",
    CLEAN(
        SUBSTITUTE(
            SUBSTITUTE(TRIM(C15),"and ","And"), 'Should this be "and" rather than "and " to match the "Bus" and "Car"?
            CHAR(32),
            ""
        )
    ),
    IF(I15="Bus",
        CLEAN(
            SUBSTITUTE(
                SUBSTITUTE(TRIM(C15),"and","And"),
                CHAR(32),
                ""
            )& "B1"
        ),
        IF(I15="Car",
            CLEAN(
                SUBSTITUTE(
                    SUBSTITUTE(TRIM(C15),"and","And"),
                    CHAR(32),
                    ""
                )
            ), 'Should this bracket be after the "C1" instead of here?
            ""
        )& "C1"
    )
)

现在，跟踪I15是否为空：I15不是“卡车”而I15不是“公共汽车”，所以我们得到：

=IF(FALSE,
    N/A,
    IF(FALSE,
        N/A,
        IF(I15="Car",
            CLEAN(
                SUBSTITUTE(
                    SUBSTITUTE(TRIM(C15),"and","And"),
                    CHAR(32),
                    ""
                )
            ), 'Should this bracket be after the "C1" instead of here?
            ""
        )& "C1"
    )
)

简化下来，你会得到：

IF(I15="Car",
    CLEAN(
        SUBSTITUTE(
            SUBSTITUTE(TRIM(C15),"and","And"),
            CHAR(32),
            ""
        )
    ),
    ""
)& "C1"

但是，I15是空白，而不是“汽车”，所以它变成IF(FALSE, N/A, "") & "C1" - 意思是，如果I15不是“公共汽车”或“卡车”，它将总是说“C1”。

此外，您可能可以将代码简化为=CLEAN(SUBSTITUTE(SUBSTITUTE(TRIM(C15),"and","And"),CHAR(32),"")) & IF(I15="Bus", "B1", IF(I15="Car", "C1", ""))

如果你可以在某处设置一个表，你可以将IF语句更改为VLOOKUP，或者如果你有一个下拉值表，你可以使用CHOOSE(MATCH(..))
