Say I have a Xtext grammar which allows me to enter 2D arrays as follows:
DataSheet x[3][3] = { [label1, label2, label3],
[10.0, 5.0, 2.0],
[0.84, 0.2, -0.44] };
Now this matrix could have lots of rows and/or the user may need to change specific cells often. Rather, than searching through the matrix, I want to provide a Table editor that can be used to create/edit this DataSheet block. When the user closes the table editor, all the matrix content gets formatted/updated using the Xtext grammar.
So when the user starts typing 'DataSheet', there should be an option where he/she can switch to a TableEditor window (which blocks the rest of the Eclipse window upon focus), supply the values there, close the window (and now Eclipse is back to focus), and see the code above. Is it possible to do this in Xtext?
Of course I will write the java code for the table editor but how to integrate it into the Xtext editor? Thanks for any ideas.

I am sure this could be done, but it won't be easy.
You could register an IAutoEditStrategy to trigger the opening of the
table editor, then take the live model from the running editor and apply
the changes made in your able editor using the IDocumentEditor API.
See the domainmodel example for auto-edit and the GMF example for
reconciling an Xtext editor with changes on the semantic model.
