作为以下问题的后续行动:

How do I delete all characters after the first space in a cell?

我需要的是将这个功能从第M2行应用到第M列末尾的最后一个条目。如果我有这个代码,我怎么能这样做:

Sub TMP()

    Dim strCodeWithDesc As String
    Dim strCodeOnly As String
    strCodeWithDesc = Range("M2").Value
    strCodeOnly = Left(strCodeWithDesc, InStr(strCodeWithDesc, " ") - 1)
    Range("M2").Value = strCodeOnly

End Sub

这种方法的有效性将依赖于每个单元的数据到达第一个空间的距离。我使用了99个字符的任意最大位置,这应该涵盖大多数情况。

使用Range.Replace method将每个空格转换为99个空格后,使用Range.TextToColumns method执行xlFixedWidth。通过分配正确的xlColumnDataType,只保留第一个“列”; TextToColumns会自动修剪多余的空格。

struct Node 
{
    int data;
    Node * next;
    Node * prev;

    Node() : next(nullptr), prev(nullptr) {} // <<<<<<<<<<<<<<<<<<<
};

如果您开始对几百个单元格执行此操作,TextToColumns优于循环遍历每个单元格并单独解析该值的优势将很快变得明显。

keep_first_word_before
keepFirstWord()之前的样本数据

keep_first_word_after
keepFirstWord()之后的样本数据

考虑:

Sub Paolo()
    Dim r As Range

    For Each r In Range("M2:M" & Cells(Rows.Count, "M").End(xlUp).Row).Cells.SpecialCells(xlCellTypeConstants)
        r.Value = Split(r.Value, " ")(0)
    Next r
End Sub

注:

如果单元格不包含空格,则保持不变。

请尝试以下代码:

Sub TMP()

Dim strCodeWithDesc As String
Dim strCodeOnly As String
Dim R as range
For Each R in Range(Range("M2"), Range("XFD2").end(xltoleft))
   strCodeWithDesc = R.Value
   strCodeOnly = Left(strCodeWithDesc, InStr(1,strCodeWithDesc, " ",vbTextCompare) - 1)
   R.Value = strCodeOnly
Next R

End Sub

如果您使用的是Excel 2003或更早版本,请使用VI2而不是XFD2

见下文

除了TMP减少

Option Explicit

Sub main()
Dim ws As Worksheet
Dim lastRow As Long, i As Long

Set ws = ThisWorkbook.Worksheets("CodeAndDesc") '<== set it as per your needs

With ws
    lastRow = .Cells(.Rows.Count, 13).End(xlUp).row
    For i = 2 To lastRow
        Call TMP(.Cells(i, 13))
    Next i
End With

End Sub


Sub TMP(rng As Range)
With rng
    .Value = Left(.Value, InStr(.Value, " ") - 1)
End With
End Sub
