Copy data from worksheet to html file to mail - vba

Question

I gather the data from different Excel sheets and paste the table and content in one sheet and then push that to html file to Outlook.
While pasting the data from the sheet to html file, it is calculating the number of columns in which the data is present.
For Example in one sheet I have pasted text which is around 500 characters on the very first row. On the next row I have pasted a 5*10 table. While copying data to html file it is calculating only 10 columns and copying the data which is in yellow in screenshot.
How do I copy all the data from Excel to html file.
If I use Sheet.UsedRange then on the basis of column it is copying data.
Code:
Dim rng As Range
Dim OutApp As Object
Dim OutMail As Object
With Application
.EnableEvents = False
.ScreenUpdating = False
End With
Dim htmlContent
Dim RangetoHTML
Dim lastColumn
Dim lastRow
Dim LastCol
Dim TempFile As String
TempFile = Environ$("temp") & "\" & Format(Now, "dd-mm-yy h-mm-ss") & ".htm"
For Each ws In ActiveWorkbook.Worksheets
If (ws.Name "Signature" And ws.Name "URL") Then
Set rng = Nothing
Set rng = ws.UsedRange
lastRow = ws.UsedRange.Rows(ws.UsedRange.Rows.Count).Row
Set rng = Range(Cells(1, 1), Cells(lastRow, 20))
'Publish the sheet to a htm file
With ActiveWorkbook.PublishObjects.Add( _
SourceType:=xlSourceRange, _
Filename:=TempFile, _
Sheet:=ws.Name, _
Source:=ws.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)
RangetoHTML = ts.readall
ts.Close
RangetoHTML = Replace(RangetoHTML, "align=center x:publishsource=", _
"align=left x:publishsource=")
htmlContent = htmlContent & RangetoHTML
'You can also use a sheet name
'Set rng = Sheets("YourSheet").UsedRange
End If
Next ws
Set OutApp = CreateObject("Outlook.Application")
Set OutMail = OutApp.CreateItem(0)
On Error Resume Next
With OutMail
.To = "sagarwal4#dow.com"
.CC = ""
.BCC = ""
.Subject = "This is the Subject line"
.HTMLBody = htmlContent
.Send 'or use .Display
End With
On Error GoTo 0
With Application
.EnableEvents = True
.ScreenUpdating = True
End With
Set OutMail = Nothing
Set OutApp = Nothing

Use something like this instead:
Dim lastCell As Excel.Range
Set lastCell = Cells.Find(What:="*", After:=Cells(1, 1), Lookat:=xlPart, _
LookIn:=xlFormulas, SearchOrder:=xlByRows, _
SearchDirection:=xlPrevious, MatchCase:=False)
Range("A1", lastCell).Copy
