Height of a tabular cell & bounding boxes

Is it possible to calculate the height of a tabular cell to be reused as a value for vertical offset of the bounding box, similarly to how Hy@raisedlink takes you one line above of where the actual hypertarget is declared?

• Wouldn't it be easier just to make the entire tabular the target? – John Kormylo May 5 '14 at 3:38
• Not if there are several different targets to different cell-heights. – 1010011010 May 5 '14 at 18:12

• \target{hist} is set after "inner self", at the right side of the text. Depending on the view settings, the PDF viewer will jump to the location of the target and you will just see the empty space at the right side.
• pdfTeX supports the additional keyword pre for \vadjust. This helps to put a target just above the current box at the left side of the surrounding vertical box. Then \target could be implemented the following way:
\newcommand*{\target}[1]{%
