Well, I guess it depends on the meaning of the word "tables".
Check this out:
"Tables represent relationships between data. Authors specify these relationships in the document language and specify their presentation in CSS, in two ways: visually and aurally.
Authors may specify the visual formatting of a table as a rectangular grid of cells. Rows and columns of cells may be organized into row groups and column groups. Rows, columns, row groups, row columns, and cells may have borders drawn around them (there are two border models in CSS2). Authors may align data vertically or horizontally within a cell and align data in all cells of a row or column.
Authors may also specify the aural rendering of a table; how headers and data will be spoken. In the document language, authors may label cells and groups of cells so that when rendered aurally, cell headers are spoken before cell data. In effect, this "serializes" the table: users browsing the table aurally hear a sequence of headers followed by data."
