Revision Content

The HTML Table Header Cell Element (<th>) defines a cell that is a header for a group of cells of a table. The group of cells that the header refers to is defined by the {{ htmlattrxref("scope", "th") }} and {{ htmlattrxref("headers", "th") }} attribute.

Attributes

Like all other HTML elements, this element supports the global attributes.

{{ htmlattrdef("abbr") }} {{ obsolete_inline() }} in {{ HTMLVersionInline("5") }}

 

{{ htmlattrdef("align") }} {{ Deprecated_inline() }} in {{ HTMLVersionInline("4") }}, {{ obsolete_inline() }} in {{ HTMLVersionInline("5") }}
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 cell
  • center, centering the content in the cell
  • right, aligning the content to the right of the cell
  • justify, inserting spaces into the textual content so that the content is justified in the cell
  • char, aligning the textual content on a special character with a minimal offset, defined by the {{ htmlattrxref("char", "th") }} and {{ htmlattrxref("charoff", "th") }} attributes {{ unimplemented_inline("2212") }}.

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Note: Do not use this attribute as it is obsolete (not supported) in the latest standard.
  • To achieve the same effect as the left, center, right or justify values, use the CSS {{ cssxref("text-align") }} property on it.
  • To achieve the same effect as the char value, in CSS3, you can use the value of the {{ htmlattrxref("char", "th") }} as the value of the {{ cssxref("text-align") }} property {{ unimplemented_inline() }}.
{{ htmlattrdef("axis") }} {{ obsolete_inline() }} in {{ HTMLVersionInline("5") }}
{{ htmlattrdef("bgcolor") }} {{ Non-standard_inline() }} {{ unimplemented_inline() }}
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"
Usage note: Do not use this attribute, as it is non-standard and only implemented some versions of Microsoft Internet Explorer: the {{ HTMLElement("thead") }} element should be styled using CSS. To give a similar effect to the bgcolor attribute, use the CSS property {{ cssxref("background-color") }} instead.
{{ htmlattrdef("char") }} {{ Deprecated_inline() }} in {{ HTMLVersionInline("4") }}, {{ obsolete_inline() }} in {{ HTMLVersionInline("5") }}{{ unimplemented_inline("2212") }}
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 {{ htmlattrxref("align", "th") }} 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 {{ htmlattrxref("char", "thead") }}, in CSS3, you can use the character set using the {{ htmlattrxref("char", "th") }} attribute as the value of the {{ cssxref("text-align") }} property {{ unimplemented_inline() }}.
{{ htmlattrdef("charoff") }} {{ Deprecated_inline() }} in {{ HTMLVersionInline("4") }}, {{ obsolete_inline() }} in {{ HTMLVersionInline("5") }}{{ unimplemented_inline("2212") }}
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.
{{ htmlattrdef("colspan") }}
{{ htmlattrdef("headers") }}
{{ htmlattrdef("rowspan") }}
{{ htmlattrdef("scope") }}
{{ htmlattrdef("valign") }} {{ Deprecated_inline() }} in {{ HTMLVersionInline("4") }}, {{ obsolete_inline() }} in {{ HTMLVersionInline("5") }}
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 {{ cssxref("vertical-align") }} property on it.
