关于excel：如何找到包含特定列中数据的最后一行？

How can I find last row that contains data in a specific column?

如何找到特定列和特定工作表中包含数据的最后一行？

怎么样：

Function GetLastRow(strSheet, strColumn) As Long
Dim MyRange As Range

Set MyRange = Worksheets(strSheet).Range(strColumn &"1")
GetLastRow = Cells(Rows.Count, MyRange.Column).End(xlUp).Row
End Function

关于注释，即使最后一行中只有一个单元格有数据，这也会返回最后一个单元格的行号：

1	Cells.Find("*", SearchOrder:=xlByRows, SearchDirection:=xlPrevious).Row

您应该使用.End(xlup)，但可能不想使用65536，而是使用：

1	sheetvar.Rows.Count

这样，它适用于Excel 2007，我相信它具有65536行以上

简单快捷：

Dim lastRow as long
Range("A1").select
lastRow = Cells.Find("*",SearchOrder:=xlByRows,SearchDirection:=xlPrevious).Row

使用示例：

1
2
3
4
5

cells(lastRow,1)="Ultima Linha, Last Row. Youpi!!!!"

'or

Range("A" & lastRow).Value ="FIM, THE END"

function LastRowIndex(byval w as worksheet, byval col as variant) as long
dim r as range

set r = application.intersect(w.usedrange, w.columns(col))
if not r is nothing then
set r = r.cells(r.cells.count)

if isempty(r.value) then
LastRowIndex = r.end(xlup).row
else
LastRowIndex = r.row
end if
end if
end function

用法：

1 2	? LastRowIndex(ActiveSheet, 5) ? LastRowIndex(ActiveSheet,"AI")

所有依赖于内置行为的解决方案(例如.Find和.End)都存在没有充分记录的限制(有关详细信息，请参阅我的其他答案)。

我需要一些东西：

查找特定列中的最后一个非空单元格(即具有任何公式或值，即使它是一个空字符串)
依靠行为明确的原语
与自动过滤器和用户修改一起可靠地工作
在10,000行上尽可能快地运行(要在Worksheet_Change处理程序中运行而不会变慢)
...性能不会因意外数据或格式置于表格末尾(约100万行)而下降

下面的解决方案：

使用UsedRange查找行号的上限(通常在接近使用范围的末尾时快速搜索真正的"最后一行")；
向后查找给定列中包含数据的行；
...使用VBA数组来避免单独访问每一行(如果UsedRange中有很多行，我们需要跳过)

(没有测试，对不起)

' Returns the 1-based row number of the last row having a non-empty value in the given column (0 if the whole column is empty)
Private Function getLastNonblankRowInColumn(ws As Worksheet, colNo As Integer) As Long
' Force Excel to recalculate the"last cell" (the one you land on after CTRL+END) /"used range"
' and get the index of the row containing the"last cell". This is reasonably fast (~1 ms/10000 rows of a used range)
Dim lastRow As Long: lastRow = ws.UsedRange.Rows(ws.UsedRange.Rows.Count).Row - 1 ' 0-based

' Since the"last cell" is not necessarily the one we're looking for (it may be in a different column, have some
' formatting applied but no value, etc), we loop backward from the last row towards the top of the sheet).
Dim wholeRng As Range: Set wholeRng = ws.Columns(colNo)

' Since accessing cells one by one is slower than reading a block of cells into a VBA array and looping through the array,
' we process in chunks of increasing size, starting with 1 cell and doubling the size on each iteration, until MAX_CHUNK_SIZE is reached.
' In pathological cases where Excel thinks all the ~1M rows are in the used range, this will take around 100ms.
' Yet in a normal case where one of the few last rows contains the cell we're looking for, we don't read too many cells.
Const MAX_CHUNK_SIZE = 2 ^ 10 ' (using large chunks gives no performance advantage, but uses more memory)
Dim chunkSize As Long: chunkSize = 1
Dim startOffset As Long: startOffset = lastRow + 1 ' 0-based
Do ' Loop invariant: startOffset>=0 and all rows after startOffset are blank (i.e. wholeRng.Rows(i+1) for i>=startOffset)
startOffset = IIf(startOffset - chunkSize >= 0, startOffset - chunkSize, 0)
' Fill `vals(1 To chunkSize, 1 To 1)` with column's rows indexed `[startOffset+1 .. startOffset+chunkSize]` (1-based, inclusive)
Dim chunkRng As Range: Set chunkRng = wholeRng.Resize(chunkSize).Offset(startOffset)
Dim vals() As Variant
If chunkSize > 1 Then
vals = chunkRng.Value2
Else ' reading a 1-cell range requires special handling <http://www.cpearson.com/excel/ArraysAndRanges.aspx>
ReDim vals(1 To 1, 1 To 1)
vals(1, 1) = chunkRng.Value2
End If

Dim i As Long
For i = UBound(vals, 1) To LBound(vals, 1) Step -1
If Not IsEmpty(vals(i, 1)) Then
getLastNonblankRowInColumn = startOffset + i
Exit Function
End If
Next i

If chunkSize < MAX_CHUNK_SIZE Then chunkSize = chunkSize * 2
Loop While startOffset > 0

getLastNonblankRowInColumn = 0
End Function

这是查找最后一行，最后一列或最后一个单元格的解决方案。它解决了找到的列的A1 R1C1参考样式难题。希望我能给予荣誉，但找不到/记住我从哪里得到的，所以谢谢！谁将原始代码发布到任何地方的人。

Public Function LastData(rCol As Range) As Range
Set LastData = rCol.Find("*", rCol.Cells(1), , , , xlPrevious)
End Function

用法：?lastdata(activecell.EntireColumn).Address

我想使用UsedRange添加一种更可靠的方法来查找最后使用的行：

1	lastRow = Sheet1.UsedRange.Row + Sheet1.UsedRange.Rows.Count - 1

同样，找到最后使用的列，您可以看到

enter image description here

立即窗口中的结果：

1 2	?Sheet1.UsedRange.Row+Sheet1.UsedRange.Rows.Count-1 21

1	Last_Row = Range("A1").End(xlDown).Row

只是为了验证，假设您要使用单元格C1中的数据打印最后一行的行号。

Range("C1").Select
Last_Row = Range("A1").End(xlDown).Row
ActiveCell.FormulaR1C1 = Last_Row

Public Function GetLastRow(ByVal SheetName As String) As Integer
Dim sht As Worksheet
Dim FirstUsedRow As Integer 'the first row of UsedRange
Dim UsedRows As Integer ' number of rows used

Set sht = Sheets(SheetName)
''UsedRange.Rows.Count for the empty sheet is 1
UsedRows = sht.UsedRange.Rows.Count
FirstUsedRow = sht.UsedRange.Row
GetLastRow = FirstUsedRow + UsedRows - 1

Set sht = Nothing
End Function

sheet.UsedRange.Rows.Count：重复使用的行数，不包括使用的第一行上方的空行

如果第1行为空，最后使用的行为10，UsedRange.Rows.Count将返回9，而不是10。

此函数计算UsedRange的第一行数加上UsedRange行数。

Sub test()
MsgBox Worksheets("sheet_name").Range("A65536").End(xlUp).Row
End Sub

由于"A65536"，因此正在列A中寻找值。

第一行将光标移动到该列的最后一个非空行。第二行打印该列行。
