wikitable This class represents Wikipedia's favored style for data tables.
toccolours This class gives the template borders and colors similar to that of the Table of Contents of a page. Do not use id="toc" instead of this, as it risks breaking some scripts and causing other problems (every id= value on a page must be unique). toccolours is not used much anymore, but used to be used for footer templates etc.
border-collapse:collapse This style will eliminate 3-d style borders created by the border attribute and collapse them in 1px wide borders. This property will override cellspacing! To define similar whitespace, use the border-spacing property (although it is not possible to have both border-spacing and border-collapse for the same table).
float:right and clear:right These styles are used to move a table to the right-hand side of the screen. Float right is equivalent to align="right" The clear code property makes it impossible for the movement to be blocked by another box or picture: the template will automatically move under it.
Margins and sizes
margin:0 0 0.5em 1em; This style prevents text from running straight to the template by saving blank space. It should be used on boxes which are floated right (using float: right;).
margin:0 1em 0.5em 0; This performs the same function as the style directly above, but should be used for boxes which are floated left (using float: left;).
