| /* |
| 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. |
