com.mckoi.database.FilterTable
public class FilterTable
A table that is a filter for another table. By default, all Table methods are implemented to call the parent. This class should be used when we want to implement a Table filter of some kind. For example, a filter for specific columns, or even rows, etc.
NOTE: For efficiency reasons, this will store SelectableScheme objects generated by the parent like VirtualTable.
