Reformat should (conditionally) align DataTables

[genthaler]

Feature: Autoformat of DataTables 
    In order to improve readability of Features
    As a Feature author
    I want the Natural plugin to automatically align column delimiters in DataTables
Scenario: Formatting a feature file with one or more DataTables 
    should align the pipe symbols.
    # This should work similarly to the ruby cucumber --autoformat argument;
    # notwithstanding the feature is being removed from there.
    Given a feature file

I agree this feature will bring extra value to the plugin: can you implement it?

Basically we'll have to determine the length of the longest element in each column then go back and the necessary padding to each row for each element in that column and repeat the whole process for each column.

Care should be taken to consider non rectangular tables, but we can leave that for a future improvement.

The source code hook for this should be CucumberFormatter.java file, though I'm not sure how the code can be linked to the formatter: some reasearch on the API is needed.

I tried setting up Eclipse to build the project, but had all sorts of problems. Could you please add some info to the Contribute page on what versions of Eclipse, plugins, JVM etc are working for you?

Hi Gunter, I just downloaded the latest and greatest Xtext bundle and, apart for a trivial error on one little missing bundle, everything worked fine... I'm currently using Eclipse Luna 64bit on a Window 7 64bit machine running a JDK 7 64bit, but I've succesfully built the project on a Linux 64bit and on a Windows XP 32bit machine in the past with no modifications and much older Eclipse and Xtext versions...

Can you please describe the errors you are getting?

An example of how this can be done may be found here: https://de.slideshare.net/meysholdt/xtexts-new-formatter-api

Unfortunately, it will involve some semi-complicated AST updates, so this will probably not make it into next. It is totally doable when we are ready for a major AST overhaul however.

[drkstr101]

The capability now exits in next to do this, but the custom formatting rules need to be implemented. No change needed on Issue status.
