provide TableRegion/Grid examples

[bertsky]

The PAGE-XML specification contains means to describe the inner structure of a TableRegion (i.e. as a coordinate matrix via Grid/GridPoints/@points).

However, so far there is no single document among assets, structural GT (1000pages / current repo) and text GT (dta / old repo) with an instance of this. (There's also no example in the PAGE-XML specification repo.)

We need these kinds of data both for making our processors table-capable and as training/evaluation data for layout analysis.

@tboenig do we have table GT yet?

@bertsky Can I add https://github.com/OCR-D/core/blob/master/tests/model/TEMP1_Gutachten2-2.xml to assets?

Sure. Just don't advertise it as "GT". Also, this still does not give an example of the Grid/GridPoints/@points annotation...

[kba]

True, but I wanted to ask anyway, since we're using it in the core tests extensively :-)

@tboenig Can we create samples with Grid/Tables?

@bertsky Can you provide the image for the PAGE? I don't know what this document is about except that it contains nested regions :)

Sorry, of course: It's already online here (cannot post TIFFs directly).
