row 'r1' under column 'c1' marked with the time 'ts1', do:

The same commands also can be run on a table reference. Suppose you had a reference
t to table 't1', the corresponding command would be:

For experts, there is an additional option -- CACHE_BLOCKS -- which
switches block caching for the scanner on (true) or off (false). By
default it is enabled. Examples:
