The Format-Table cmdlet formats the output of a command as a table with the selected properties of the object in each column. The object type determines the default layout and properties that are displayed in each column. You can use the Property parameter to select the properties that you want to display. PowerShell uses default formatters to define how object types are displayed. You can use .ps1xml files to create custom views that display an output table with specified properties. After a custom view is created, use the View parameter to display the table with your custom view. For more information about views, see about_Format.ps1xml. You can use a hash table to add calculated properties to an object before displaying it and to specify the column headings in the table. To add a calculated property, use the Property or GroupBy parameter. For more information about hash tables, see about_Hash_Tables.
