BlockTabSeparated
-----------------

Data is not written by row, but by column and block.
Each block consists of parts of columns, each of which is written on a separate line.
The values are tab-separated. The last value in a column part is followed by a line break instead of a tab.
Blocks are separated by a double line break.
The rest of the rules are the same as in the TabSeparated format.
This format is only appropriate for outputting a query result, not for parsing.
