  div#table
  {
  border-left: 100px solid white;

  /*
  The width of a CSS table is the distance from the left inner padding
  edge to the right inner padding edge (including the table border-spacing
  but excluding table padding and table borders).

  Therefore the 'padding: 0 33px;' is not involved in the used width
  calculation and 'border-left: 100px solid white;' and
  'border-right: 100px solid white;' are not involved in the used
  width calculation.

  The width of a CSS table is given by the greater of the value of
  the 'width' property as set for the CSS table and the sum of the columns
  width (plus border spacing):

  max(set width, sum of columns width plus border spacing)

  Here, the set width is 200px.

  The sums of columns' width plus border spacing is given by:

   52px   (left-most border-spacing)
 +
    0px   (div#td's width)
 +
   52px   (right-most border-spacing)
  ======
  104px : sum of columns plus border spacing

  200px (set width of table)
 -
  104px (sum of columns plus border spacing)
  =====
   96px : such extra (exceeding) 96px width will be distributed over
  the columns, therefore given to the unique cell of such div#table

  So, the div#td should be 96px wide, 16px tall and painted black.
