Here's a user defined function you could use
Code:
Function konkat(ByVal r As Range, Optional s As String = ",")
For Each c In r
konkat = konkat & c.Value & s
Next
konkat = Left(konkat, Len(konkat) - Len(s))
End Function
A1:A8 = the digits 1 to 8
=konkat(A1:A8) returns <TABLE style="WIDTH: 42pt; BORDER-COLLAPSE: collapse" border=0 cellSpacing=0 cellPadding=0 width=56 x:str><COLGROUP><COL style="WIDTH: 42pt" width=56><TBODY><TR style="HEIGHT: 11.25pt" height=15><TD style="BORDER-BOTTOM: #ece9d8; BORDER-LEFT: #ece9d8; BACKGROUND-COLOR: transparent; WIDTH: 42pt; HEIGHT: 11.25pt; BORDER-TOP: #ece9d8; BORDER-RIGHT: #ece9d8" height=15 width=56>
