  • where are those line corners are seen? Commented Jan 9, 2011 at 11:51
  • @Herbert, if you compile the code above, view the output and zoom-in near the top right corner, you will see the excessive lines. Commented Jan 9, 2011 at 11:58
  • @Herbert, 400% zoom will show the excessive. Commented Jan 9, 2011 at 11:59
  • @xport: this doesn't happen with my code changes ... Commented Jan 9, 2011 at 12:12
  • @Herbert, your solution only solves the spacing. Unfortunately, the vertical and horizontal rules now get separated using your setting. They should touch each other and make a GOOD corner. :-) Commented Jan 9, 2011 at 12:32

Using @Herbert's info, I did some trial and error.

I changed \Big| to \rule{}. You can see the modification in the part enclosed by %===========================
