Old post, but I was just trying to do something similar and wanted to share what I came up with.
My Use Case:
Table A and Table B are side-by-side on the same dashboard row. Table A will always show every row (between 15 and 40), but Table B will have hundreds of rows. I wanted the maximum rows of Table B to be dynamically constrained to the currently-displayed row count of Table A.
My Solution:
Table A:
<search>
<query>blahBlah</query>
<done>
<eval token="rowsTableA">tonumber('job.resultCount')</eval>
</done>
</search>
Table B:
<option name="count">$rowsTableA$</option>
Hope this might help someone if you're in a similar situation! 🙂

Perhaps late to the party here, but you could always create an HTML dashboard, and then with careful CSS positioning you can arrange single-value searches around whatever image(s) you're using for your topology. Takes longer to set up, but if you don't have ES / ITSI it's an excellent way to manually create "glass tables". 🙂
