TBColumn
 Provide column objects for TBrowse objects
------------------------------------------------------------------------------
 Description

     A TBColumn object is a simple object containing the information needed
     to fully define one data column of a TBrowse object.

 Examples

     .  This example is a code fragment that creates a TBrowse object
        and adds some TBColumn objects to it:

        USE Customer NEW
        //

        // Create a new TBrowse object
        objBrowse := TBrowseDB(1, 1, 23, 79)
        //

        // Create some new TBColumn objects and
        // add them to the TBrowse object
        objBrowse:addColumn(TBColumnNew("Customer", ;
              {|| Customer->Name}))
        objBrowse:addColumn(TBColumnNew("Address", ;
              {|| Customer->Address}))
        objBrowse:addColumn(TBColumnNew("City", ;
              {|| Customer->City}))
        .
        . <statements to actually browse the data>
        .
        CLOSE Customer
