An example of two simple tables , with exercises to try. If present, borders are drawn around all table cells. Values are left , center , and right . The default is center. It can also specify that all the cells in the row should be vertically aligned to the same baseline.
Values are top , middle bottom , and baseline .
By default lines of text inside of table cells are broken up to fit within the overall cell width. Be cautious in use of this attribute as it can result in excessively wide cells. A span that extends into rows that were never specified with a TR will be truncated. First they gain the ability emphasize some tables with respect to others, a table with a border of four containing a sub-table with a border of one looks much nicer than if they both share the same default border width. Second, by explicitly setting border to zero they regain that space originally reserved for borders between cells, allowing particularly compact tables.
