Table Borders: BORDER, FRAME and RULES
For the next few pages we're going to use three <TABLE ...> attributes:
BORDER |
size of outside border |
FRAME |
which outside borders are displayed |
RULES |
which inside borders are displayed |
These three attributes can get pretty confusing because they tend to change each other's defaults. For example, if you don't use
BORDER then the default for
RULES is NONE. However, if you do use BORDER (but only values greater than zero) or if you use any value of
FRAME besides
VOID
then RULES defaults to
ALL. Likewise, RULES changes FRAME's defaults.
To keep things simple it's usually a good idea to follow a simple rule: if you use either FRAME or RULES use them both and also use BORDER. That avoids confusion about what is defaulting to what. We'll follow that example in this guide. So, for example, to create a table with no inner borders we'll use all three attributes like this:
<TABLE BORDER=1 RULES=NONE FRAME=BOX>
which gives us this table
| watermelon | grapes |
| peaches | bananas |
|
