## Class Table

- Object
- - Table

-     public class Table
      extends Object

  Generic class for handling tabular data, typically from a CSV, TSV, or other sort of spreadsheet file.

  CSV files are comma separated values, often with the data in quotes. TSV files use tabs as separators, and usually don't bother with the quotes.

  File names should end with .csv if they're comma separated.

  A rough "spec" for CSV can be found here.
