Attributes
This element includes the global attributes.
Deprecated attributes
align
-
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 thechar
andcharoff
attributes.
If this attribute is not set, the
left
value is assumed.Warning: Do not use this attribute as it is obsolete (not supported) in the latest standard.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
orjustify
values, use the CSStext-align
property on it. - To achieve the same effect as the
char
value, in CSS3, you can use the value of thechar
as the value of thetext-align
property.
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:
black
= "#000000"green
= "#008000"silver
= "#C0C0C0"lime
= "#00FF00"gray
= "#808080"olive
= "#808000"white
= "#FFFFFF"yellow
= "#FFFF00"maroon
= "#800000"navy
= "#000080"red
= "#FF0000"blue
= "#0000FF"purple
= "#800080"teal
= "#008080"fuchsia
= "#FF00FF"aqua
= "#00FFFF"
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 propertybackground-color
, on the relevant<td>
or<th>
elements. char
-
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 tochar
, this attribute is ignored.Note: Do not use this attribute as it is obsolete (and not supported) in the latest standard.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 thechar
attribute as the value of thetext-align
property. charoff
-
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Note: Do not use this attribute as it is obsolete (and not supported) in the latest standard.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
-
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 asbottom
.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;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.
