Attributes

This element includes the global attributes.

align 已废弃 HTML4.01, 已废弃 HTML5

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 cells
• center, centering the content in the cells
• right, aligning the content to the right of the cells
• justify, widening the spaces in the textual content so that the content is justified in the cells
• char, aligning the textual content on a special character with a minimal offset, defined by the char and charoff attributes 未实现 (查看 bug 2212)

If this attribute is not set, the parent node's value is inherited.

Note: Do not use this attribute as it is obsolete (not supported) in the latest standard.

• To achieve the same effect as the left, center, right or justify values, use the CSS text-align property on it.
• To achieve the same effect as the char value, in CSS3, you can use the value of the char as the value of the text-align property 未实现.

bgcolor 已废弃 HTML4.01, 已废弃 HTML5

This attribute defines the background color of each cell of the row. It can be either an hexadecimal #RRGGBB or #RGB value or a color keyword.

Usage note: the <tr> element should be styled using CSS. To give a similar effect to the bgcolor attribute, use the CSS property background-color.

char 已废弃 HTML4.01, 已废弃 HTML5

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Note: Do not use this attribute as it is obsolete (and not supported) in the latest standard.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 未实现.

charoff 已废弃 HTML4.01, 已废弃 HTML5

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Note: Do not use this attribute as it is obsolete (and not supported) in the latest standard.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 已废弃 HTML4.01, 已废弃 HTML5

This attribute specifies the vertical alignment of the text within each row of cells of the table header. Possible values for this attribute are:

• 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. If characters are all of the size, this has the same effect as bottom.
• bottom, which will put the text as close to the bottom of the cell as it is possible;
• middle, which will center the text in the cell;
• and top, which will put the text as close to the top of the cell as it is possible.

Note: Do not use this attribute as it is obsolete (and not supported) in the latest standard: instead set the CSS vertical-align property on it.
