Comment 1 for bug 260327

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.
