Translation:This table is low.
Hikui (低い), i do believe, is both low and short... My dictionary has it as meaning low, short, humble. But then again... Duo is using another word, mijikai (短い) to mean short. Someone said.. One is short as in not long.. And the other is short as in not tall. So.. Idunno.. They are both comin up descriptively short to me. :D
