如果下面的列有1，则连接顶行单元格 [英] Concatenate top row cells if column below has 1

问题描述

我正在查看一个具有命名列的1和0的大型数据库，如下所示：

 红色蓝色绿色橙色紫色
──────────────────────────────────────────────────────────────────────────────────────────── 0 0 0 
  

我想连接所有的标题（按行），其中行有一个在该标题之下。所以理想情况下，第一个等于绿色，紫色，第二个只会读取蓝色。我有大量数据，所以任何嵌套一百个IF功能的任何东西都没有意义。

我尝试过

= IF（B1：B5 = CONCATENATE（A1：A5），）

和几件事情接近，但我没有找到一个明显的方式为拿到它，为实现它。我也没有时间或足够的知识来处理VBA。感谢所有的帮助，谢谢！

解决方案

超过几个单元格的字符串连接最好留给VBA用户即使没有设置条件，定义的功能（也就是UDF ）。 kbd> + F11 ，当VBE打开时，我可以使用下拉菜单插入►模块（ Alt + I ，中号）。将以下内容粘贴到新窗格中，名称类似于 Book1 - Module1（Code）。

 公共功能condition_concat（rSTRs As Range，rCRITs As Range，可选sDELIM As String =，）
 Dim c As Long，sTMP As String 
对于c = 1 To Application.Min（rSTRs.Cells.Count， rCRITs.Cells.Count）
如果CBool​​（rCRITs（c）.Value2）Then _ 
 sTMP = sTMP& rSTR（c）.Value& sDELIM 
下一步c 
 conditional_concat = Left（sTMP，Application.Max（Len（sTMP） -  Len（sDELIM），0））
结束函数
  

点击 Alt + Q 返回到您的工作表。像任何本地的Excel工作表函数一样使用这个UDF。语法是

  conditional_concat（< strings的范围><条件范围>，[可选]<分隔符作为字符串>）
  

G2中的公式是，

  = conditional_concat（A $ 1：E $ 1，A2：E2）
  

填充

I'm looking at a large database of 1s and 0s with named columns, like this:

red    blue   green  orange purple
────── ────── ────── ────── ──────
0      0      1      0      1 
0      1      0      0      0 

I want to concatenate all the headings (by row) where the row has a "1" below that heading. So ideally the first one would equal "green, purple" and the second would just read "blue". I have a large amount of data so anything with nesting of a hundred "IF" functions doesn't make sense.

I've tried

=IF(B1:B5=1, CONCATENATE(A1:A5), "")

and a couple things close to that, but I'm not finding an obvious way to get it. I also don't really have time or enough knowledge to deal with VBA. I appreciate all help, thanks!

解决方案

String concatenation over more than a few cells is best left to a VBA User Defined Function (aka UDF) even without setting criteria. Your situation of "nesting of a hundred "IF" functions" would certainly put it in this category.

Tap Alt+F11 and when the VBE opens, immedaitely use the pull-down menus to Insert ► Module (Alt+I,M). Paste the following into the new pane titled something like Book1 - Module1 (Code).

Public Function conditional_concat(rSTRs As Range, rCRITs As Range, Optional sDELIM As String = ", ")
    Dim c As Long, sTMP As String
    For c = 1 To Application.Min(rSTRs.Cells.Count, rCRITs.Cells.Count)
        If CBool(rCRITs(c).Value2) Then _
            sTMP = sTMP & rSTRs(c).Value & sDELIM
    Next c
    conditional_concat = Left(sTMP, Application.Max(Len(sTMP) - Len(sDELIM), 0))
End Function

Tap Alt+Q to return to your worksheet. Use this UDF like any native Excel worksheet function. The syntax is,

conditional_concat(<range of strings>, <range of conditions>, [optional] <delimiter as string>)

      

The formula in G2 is,

=conditional_concat(A$1:E$1, A2:E2)

Fill down as necessary.
