.DESCRIPTION
Converts objects into a DataTable, which are used for DataBinding.

.PARAMETER InputObject
The input to convert into a DataTable.

.PARAMETER Table

.PARAMETER RetainColumns
This switch tells the function to keep the DataTable's existing columns.

.PARAMETER FilterWMIProperties
This switch removes WMI properties that start with an underline.
