A simple FileHandler which allows to edit files with tabular data.

It is by no means a replacement for OpenOffice Calc or MS Excel, but allows to perform some basic operations, like re-ordering rows and columns, transposition (turning rows into columns and vice versa) and changing the CSV format (using different delimiters, encoding, quoting).

It also supports clipboard interaction by storing its data in various flavors which are commonly understood by a number of other applications.

It also comes with its own format for storing such data which is very much alike the standard HTML format for tables. In that format it allows to store multiple tables (called sheets) in a single file and will persist any applied layout and styling.
