This attribute controls the background color of the cell. The value is either a named color or an RGB value.

This attribute has a unitdim value indicating the amount of white space to be left between a cell's bottom rule and the edge of the box in which text is actually displayed. Permissible values are in, pt, pi, px, cm, or mm meaning inches, points, picas, pixels, centimeters, or millimeters.

In HTML tables, setting this attribute (px is the only supported unit) will set all four margin attributes for all the cells in the table. You can achieve the same effect by setting the CELLPADDING set table attribute.

The following values are also valid, but cannot be used to control the horizontal text justification for the cell: start, end, or inherit.

Character alignment is not effective in HTML outputs. Browsers are not required to support it, and they do not.

This attribute is a single character on which to horizontally align the text in a column of cells. This character alignment scheme is used only if the HALIGN attribute is set to character.

This attribute is a number between zero (0) and 100 indicating the desired location of the alignment character given by the HALIGN_CHAR attribute. Zero (0) places the character to the extreme left side of the cell, 100 places the character to the extreme right of the cell. This offset is used only if the HALIGN attribute is set to character.

This attribute applies only to HTML tables. This attribute is 0 if the cell is a data cell (td) and is 1 if the cell is a header cell (th).
