Jeffery Hicks shows us how we can format Powershell files through XML:
My PSScriptTools module (which you can install from the PowerShell Gallery) now includes a command called New-PSFormatXML. The command is designed to analyze an object and by default create a table view of all properties, although you can specify which properties to include. The format.ps1xml file will autosize the table but you can remove the directive and use the widths which are best guesses. Expect some trial and error when defining a new view.
Read on for a couple demonstrations.
