Convert range to table without changing column width / formatting

Yes I know I can record a macro, but I don't realise I could use it as a way to find out the code of a table style.
It's brilliant. Thanks for the tip.

As for random table names, this should create a table name with a random number between 100,000 and 1,000,000 (and set the table style to None):

Sub Macro1()
Dim newRand As Long
Randomize
newRand = CLng((1000000 - 100000 + 1) * Rnd + 100000)

ActiveSheet.ListObjects.Add(xlSrcRange, Range(Selection.Address), , xlYes).Name = "Table" & newRand
With ActiveSheet.ListObjects("Table" & newRand)
    .ShowTableStyleRowStripes = False
    .ShowHeaders = True
    .TableStyle = ""
    .ShowTotals = True
End With
End Sub

Thank you very much.
