/*
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.
