Attributes
Includes the Global Attributes.
Name | Version | Description | ||||||||||||||||||||||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
align |
HTML 4 | This enumerated attribute specifies how horizontal alignment of each cell content will be handled. Possible values are:
If this attribute is not set, the left value is assumed. Note: Do not use this attribute as it is obsolete (not supported) in the latest standard.
|
||||||||||||||||||||||||||||||||
bgcolor |
This attribute defines the background color of each cell of the column. It is one of the 6-digit hexadecimal code as defined in sRGB, prefixed by a '#'. One of the sixteen predefined color strings may be used:
Usage note: Do not use this attribute, as it is non-standard and only implemented in some versions of Microsoft Internet Explorer: the
<thead> element should be styled using CSS. To give a similar effect to the bgcolor attribute, use the CSS property background-color , on the relevant <td> or <th> elements. |
|||||||||||||||||||||||||||||||||
char |
HTML 4 | 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Note: Do not use this attribute as it is obsolete (and not supported) in the latest standard.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. |
||||||||||||||||||||||||||||||||
charoff |
HTML 4 | This attribute is used to indicate the number of characters to offset the column data from the alignment characters specified by the char attribute.
Note: Do not use this attribute as it is obsolete (and not supported) in the latest standard.
|
||||||||||||||||||||||||||||||||
valign |
HTML 4 | This attribute specifies the vertical alignment of the text within each row of cells of the table header. Possible values for this attribute are:

vertical-align property on it. |
