Use the
IXLSWorkbook.Names or
IXLSWorksheet.Names property to return the Names collection.
Use the
Add method to create a name and add it to the collection.
The Add method's RefersTo argument must be specified in A1-style notation,
including dollar signs ($) where appropriate.
For example, if cell A10 is selected on Sheet1 and you define a name
by using the RefersTo argument '=sheet1!A1:B1', the new name actually
refers to cells A10:B10 because you specified a relative reference).
To specify an absolute reference, use '=sheet1!$A$1:$B$1'.
Use Names[index], where index is the name index number or defined name,
to return a single Name object.
