Returns a Range object that represents all the columns on the specified worksheet.
Syntax
expression.Columns
expression A variable that represents a Worksheet object.
Remarks
Using the Columns property without an object qualifier is equivalent to using ActiveSheet.Columns. If the active document isn't a worksheet, the Columns property fails.
To return a single column, use the Item property or equivalently include an index in parentheses. For example, Columns(1), Columns("A"), Columns.Item(1) and Columns.Item("A") return the first column of the active sheet.
Example
This example formats the font of column one (column A) on Sheet1 as bold.
Worksheets("Sheet1").Columns(1).Font.Bold = True
