SDL Component Suite - NTabEd

The unit NTABED contains a Delphi™ visual component which supports displaying and editing of numeric tables. Each table consists of the data table, column and row attributes, column and row headers, and a comment line. All of these items can be manipulated either interactively or programmatically. The data table is based on the class TMatrix.

The figure at right shows an example of the table editor. The editor may be widely configured to the user's requirements: column and row sizes are adjustable, display precision may set up columnwise, optional row and column attributes allow additional classification of data. In addition, NTabEd provides the full functionality of the unit MATRIX, thus allowing to apply mathematical procedures to the data. More details can be found in the online help pages.

The unit NTABED is part of the SDL Component Suite.
