content with very width lines can produce very large tables,
eg a grid cell with 2000 rel. short lines, but 1 line the size of 2000 characters, will produce a grid table of 4mb, which is not optimal.
it should be possible to specify a max table width or cell width, with a default of 200.
if a line within a codeblock within a cell gets longer than 255 characters, break the line, but use a no break here imediately after the 255th character.
during parsing, remove all \nbh\n when collating the cells.
