Here's my modified version of Ron de Bruin's function:
Function RangetoHTMLFlexWidth(rng As Range)
' Changed by Ron de Bruin 28-Oct-2006
' Working in Office 2000-2013
Dim fso As Object
Dim ts As Object
Dim TempFile As String
Dim TempWB As Workbook
TempFile = Environ$("temp") & "\" & Format(Now, "dd-mm-yy h-mm-ss") & ".htm"
'Copy the range and create a new workbook to past the data in
rng.Copy
Set TempWB = Workbooks.Add(1)
With TempWB.Sheets(1)
.Cells(1).PasteSpecial Paste:=8
.Cells(1).PasteSpecial xlPasteValues, , False, False
.Cells(1).PasteSpecial xlPasteFormats, , False, False
.Cells(1).Select
Application.CutCopyMode = False
On Error Resume Next
.DrawingObjects.Visible = True
.DrawingObjects.Delete
On Error GoTo 0
End With
'Publish the sheet to a htm file
With TempWB.PublishObjects.Add( _
SourceType:=xlSourceRange, _
Filename:=TempFile, _
Sheet:=TempWB.Sheets(1).Name, _
Source:=TempWB.Sheets(1).UsedRange.Address, _
HtmlType:=xlHtmlStatic)
.Publish (True)
End With
'Read all data from the htm file into RangetoHTML
Set fso = CreateObject("Scripting.FileSystemObject")
Set ts = fso.GetFile(TempFile).OpenAsTextStream(1, -2)
RangetoHTMLFlexWidth = ts.readall
ts.Close
RangetoHTMLFlexWidth = Replace(RangetoHTMLFlexWidth, "align=center x:publishsource=", _
"align=left x:publishsource=")
Dim startIndex As Long
Dim stopIndex As Long
Dim subString As String
'Change table width to "100%"
startIndex = InStr(RangetoHTMLFlexWidth, "<table")
startIndex = InStr(startIndex, RangetoHTMLFlexWidth, "width:") + 5
stopIndex = InStr(startIndex, RangetoHTMLFlexWidth, "'>")
subString = Left(RangetoHTMLFlexWidth, startIndex)
subString = subString & "100%"
RangetoHTMLFlexWidth = subString & Mid(RangetoHTMLFlexWidth, stopIndex)
'Close TempWB
TempWB.Close savechanges:=False
'Delete the htm file we used in this function
Kill TempFile
Set ts = Nothing
Set fso = Nothing
Set TempWB = Nothing
End Function
The changes start with the comment:
'Change table width to "100%"
It just finds the spot where the table's width is defined and sets it to 100%. The browser or outlook scales the cells to the new width, so it does the job, but it's a dirty hack, IMO.
