This attribute contains a short abbreviated description of the content of the cell. Some user-agent, like speech reader, may present it before the content itself.
Note: Do not use this attribute as it is obsolete in the latest standard: instead either consider starting the cell content by an independent abbreviated content itself or use the abbreviated content as the cell content and use the long content as the description of the cell by putting it in the title attribute.

This enumerated attribute specifies how horizontal alignment of each cell content will be handled. Possible values are:
left, aligning the content to the left of the cellcenter, centering the content in the cellright, aligning the content to the right of the celljustify, inserting spaces into the textual content so that the content is justified in the cellchar, aligning the textual content on a special character with a minimal offset, defined by the char and charoff attributes Unimplemented (see bug 2212).If this attribute is not set, the left value is assumed.

bgcolor attribute, use the
CSS property
background-color instead.
This attribute is used to set the character to align the cells in a column on.
This attribute is used to set the character to align the cells in a column on. Typical values for this include a period (.) when attempting to align numbers or monetary values. If
align is not set to
char, this attribute is ignored.
Note: Do not use this attribute as it is obsolete (and not supported) in the latest standard. To achieve the same effect as the
char, in CSS3, you can use the character set using the
char attribute as the value of the
text-align property
Unimplemented.

baseline, which will put the text as close to the bottom of the cell as it is possible, but align it on the baseline of the characters instead of the bottom of them.

This attribute is used to define a recommended cell width. Properties
cellspacing and
cellpadding may add additional space, and element
<col> width may also have some effect. In general, if a column's width is too narrow to show a particular cell properly, it, and thus the cells in it, may be widened when displayed.
