In tables, the number of styles affecting the display of objects increases dramatically. In addition to the normal containment (a table, as all other elements of a document, is always contained either within another render object, or within the body of the document at the top level), object in tables also belong to at least a cell, a row and a column, all of which have their own styles. Additionally, an object can belong to a number of table element groups, which complicates the things even more. How styles in tables work is described in more detail in the Styles in Tables topic.
