th

Provides an abbreviated form of the cell's content and may be rendered by user agents when appropriate in place of the cell's content. Abbreviated names should be short since user agents may render them repeatedly. For instance, speech synthesizers may render the abbreviated headers relating to a particular cell before rendering that cell's content.

Specifies the alignment of data and the justification of text in a cell.

This attribute may be used to place a cell into conceptual categories that can be considered to form axes in an n-dimensional space. User agents may give users access to these categories (e.g., the user may query the user agent for all cells that belong to certain categories, the user agent may present a table in the form of a table of contents, etc.). Please consult an HTML reference for more details.

This attribute specifies a single character within a text fragment to act as an axis for alignment. The default value for this attribute is the decimal point character for the current language as set by the lang attribute (e.g., the period in English and the comma in French). User agents are not required to support this attribute.

When present, this attribute specifies the offset to the first occurrence of the alignment character on each line. If a line doesn't include the alignment character, it should be horizontally shifted to end at the alignment position. When charoff is used to set the offset of an alignment character, the direction of offset is determined by the current text direction (set by the dir attribute). In left-to-right texts (the default), offset is from the left margin. In right-to-left texts, offset is from the right margin. User agents are not required to support this attribute.

This attribute assigns a class name or set of class names to an element. Any number of elements may be assigned the same class name or names. Multiple class names must be separated by white space characters.

Specifies the number of columns spanned by the current cell. The default value of this attribute is one (“1” ). The value zero (“0” ) means that the cell spans all columns from the current column to the last column of the column group (colgroup ) in which the cell is defined.

Specifies the list of header cells that provide header information for the current data cell. The value of this attribute is a space-separated list of cell names; those cells must be named by setting their id attribute. Authors generally use the headers attribute to help non-visual user agents render header information about data cells (e.g., header information is spoken prior to the cell data), but the attribute may also be used in conjunction with style sheets.

This attribute specifies the base language of an element's attribute values and text content. The default value of this attribute is unknown.

Occurs when the pointing device button is clicked over an element.

Occurs when the pointing device button is double clicked over an element.

Occurs when a key is pressed down over an element.

Occurs when a key is pressed and released over an element.

Occurs when a key is released over an element.

Occurs when the pointing device button is pressed over an element.

Occurs when the pointing device is moved while it is over an element.

Occurs when the pointing device is moved away from an element.

Occurs when the pointing device is moved onto an element.

Occurs when the pointing device button is released over an element.

Specifies the number of rows spanned by the current cell. The default value of this attribute is one (“1” ). The value zero (“0” ) means that the cell spans all rows from the current row to the last row of the table section (thead , tbody , or tfoot ) in which the cell is defined.

Specifies the set of data cells for which the current header cell provides header information. This attribute may be used in place of the headers attribute, particularly for simple tables.

This attribute specifies style information for the current element.

This attribute offers advisory information about the element for which it is set.

Specifies the vertical position of data within a cell.
