How to select next empty cell in row for a specific range?

Hi

I have a spreadsheet with with 8 columns and unlimited rows which needs to be filled in.
How can I modify my current code so that when i press enter it goes to the next empty cell in row until the column 8 ("H") then to the next row?

Currently this code only does column "A" and "B" - I need to "H"

Private Sub Worksheet_Change(ByVal Target As Range)

Dim erow As Long

erow = ActiveSheet.Cells(Rows.Count, 1).End(xlUp).Offset(1, 1).Row

If Cells(erow - 1, 1).Offset(0, 1) = "" Then

Cells(erow - 1, 1).Offset(0, 1).Select

Else: Cells(erow, 1).Select

End If
End Sub

Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Column = 8 Then
        Target.Offset(1, -7).Select
Else
   Target.Offset(0, 1).Select
   
End If

End Sub

Thanks!

However I also have an automatic sort. (To sort column C)
It sorts only columns A to C then continues with the former row. - I need to sort the whole range
Kindly see below my current code:

Dim erow As Long
erow = ActiveSheet.Cells(Rows.Count, 1).End(xlUp).Offset(1, 1).Row
Range("C:C").Select
Range("A:H").Sort Key1:=Range("C2"), Order1:=xlAscending, Header:= _
xlGuess, OrderCustom:=1, MatchCase:=False, Orientation:=xlTopToBottom, _
DataOption1:=xlSortNormal



If Cells(erow - 1, 1).Offset(0, 1) = "" Then
'Cells(erow - 1, 1).Offset(0, 1).Select

Else: Cells(erow, 1).Select
End If

Whole range sort on what parameter ?? Basically this code is sorting the whole range on the basis of C column.

I need a code that will sort my spreadsheet based on column "C"
But enable only after data is entered from "A" to "H" per row.
