table recognition is exists inside engine, and it supported at least in HTML and RTF output.
PUMA_Word32_Tables (later goes to gnTables) is responsible for this.
inside doc/pumaAPI.rtf I found description of the similar constant (in Russian, my translation) :
long Get/Set ModeTable – table recognition mode. 0 – tables are not selected, 1- columns and lines are selected, 2 – lines only, 3- no lines ( only for Apuma.dll )

The constant is used in file rshelllines.cpp, which, btw, tells that "Warning: RSL said that the lines do not have to withdraw." on any file. So i think that it should be enabled somewhere around.

Я знаю русский и проблем с чтением оригинальной документации нет (I know russian and no problems with reading original docs).

OK, I look the code and try to enable this functions.

The "lines do not have to withdraw" thing was translated using Google translator. I have no idea what it actually means. Getting a translation for that would be nice. :)

LDPUMA_Console("Предупреждение: RSL говорит, что снимать линии не надо.\n");

"снимать" is a jargon term in this context. My translation - "measure", may be "take" also appropriate term.

LDPUMA_Console("Warning: RSL said that the lines do not have to measure.\n");

btw, i found source of this error.
It comes from non initialized RVERLINE engine. To fix this we should just put
#define _USE_RVERLINE_
at the beginning of cuneiform_src/Kern/puma/c/initdone.cpp and and cuneiform_src/Kern/rstuff/sources/main/normalise.cpp.

This will enable rverline code (not sure what it is, but at least it not crashes).

I contacted by private mail one f the cuneiform developers, to ask him about tables support (because i was not able to find table selection code in layout() at all). Today i got an answer from him:

В текущей версии выделение и распознавание таблиц отключено, т.к. открытие
этого набора исходников отложило бы опубликования всего кода под BSD-like
лицензией на длительный срок (не менее 9-12 месяцев). Открытие кода по
таблицам в планах стоит, но о сроках я ничего конкретного сказать не могу.

In the current version of the code selection and recognition of the tables turned off, because opening
this set would have postponed the publication of source code under the whole BSD-like
license for a long period (not less than 9-12 months). Opening the code for
tables in the plans is, but terms are unknown.

2 JussiP i think it`s time to change this bug status to WONT`BE FIXED and to put an explanation inside readme for other project hackers.

"снимать" в таком контектсте обычно означает физическое стирание линии с изображения (на пиксельном уровне), т.е. наиболее близкое "стирать"

"снимать" in such context usualy means erase or clear line from the image (erase line pixels)
My translation - "clear" or "erase"

Thanks. I have updated the translation.
