TextTable interface definition
Quick overview
Currently the file definition only allows plain fixed length files. Supporting separated files is an open topic at the moment. You start the definition with the keyword plain followed by an identifier for the file definition. That is follow the column specification which is enclosed between the keywords begin and end, where end is stopped by a ; (Semicolon). But let’s have a look at a simple example.

Example 01
interface definition
The option left or right from the example above (the field id) is used when the table is rendered back to the file. This way you can define whether the field is left or right aligned at the file.
There are basically two different ways to define a column. You can do that eighter by defining a columns length or you can define where the column starts and ends in a single line with from and to. Using from and to there’s no validation for gaps or intersections of the column definitions.
