/**\class FWTableManagerBase FWTableManagerBase.h Fireworks/TableWidget/interface/FWTableManagerBase.h
Description: Base class for classes that work as interfaces that translate underlying data into a table form
Usage:
Classes which inherit from FWTableManagerBase are used as adapters to allow external data to be shown in tabular form
via the FWTableWidget. The table is made of three parts
1) The column headers: Each column is described by a 'title' and the title is drawn in the column header
2) The body: the actual data of the table laid out in rows and columns
3) the row headers: optional identifier for a row. If given, the row header will always be visible on the screen if any part
of the row is visible
The FWTableWidget actually draws the cells in the table by asking the FWTableManagerBase for a FWTableCellRendererBase for
a particular cell. The renderer will then be asked to draw the cell into the appropriate part of the graphics window. Therfore
it is the FWTableManagerBase's responsibility to create FWTableCellRendererBases which are appropriate for the data to be
shown in each cell of the table. See the documentation of FWTableCellRendererBase for further information.
FWTableManagerBase must also be able to sort the rows of data based on the values in a specified column.
