迭代表中每个单元格的内容并检索/存储其值的最佳方法是什么。
使用目前的方法,我无法在变量val
样品表:
Set ws = ActiveSheet
ws.Name = "sheet1"
Set tbl = ws.ListObjects("tblBor")
Application.Calculation = xlCalculationManual
ws.Calculate
With tbl.Sort
.SortFields.Clear
.SortFields.Add Key:=Range("tblBor[ID]"), SortOn:=xlSortOnValues, Order:=xlAscending
.Header = xlYes
.Apply
End With
Set rng = Range(tbl)
rows = tbl.Range.rows.Count
Columns = tbl.Range.Columns.Count
For iter = 1 To rows
For col = 1 To Columns
'Iterate through each row by each column
'val = tbl.DataBodyRange(iter, col).Value
Next col
Next iter
答案 0 :(得分:1)
您有一个ListObject
,请使用其API! ListRows
和ListColumns
是对象集合,迭代这些by several orders of magnitude的最快方法是使用For Each
循环:
Dim tblRow As ListRow
For Each tblRow In tbl.ListRows
Dim tblCol As ListColumn
For Each tblCol In tbl.ListColumns
Debug.Print "(" & tblRow.Index & "," & tblCol.Index & "): " & tblRow.Range(tblCol.Index).Value
Next
Next
如果您只想将内容收集到2D值数组中,则无需进行任何迭代-只需抓住DataBodyRange
并将其像其他“常规” Range
一样对待:
Dim contents As Variant
contents = tbl.DataBodyRange.Value
如果以后需要迭代2D变量数组,最快的方法(与上述相同)是For...Next
循环:
Dim currentRow As Long
For currentRow = LBound(contents, 1) To UBound(contents, 1)
Dim currentCol As Long
For currentCol = LBound(contents, 2) To UBound(contents, 2)
Debug.Print "(" & currentRow & "," & currentCol & "): " & contents(currentRow, currentCol)
Next
