Attributes
- align
Specifies the alignment of data and the justification of text in a cell.
Enumerated values: “left” Left-flush data/Left-justify text. This is the default value for table data.
“center” Center data/Center-justify text. This is the default value for table headers.
“right” Right-flush data/Right-justify text.
“justify” Double-justify text.
“char” Align text around a specific character. If a user agent doesn’t support character alignment, behavior in the presence of this value is unspecified.
- char
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
langattribute (e.g., the period in English and the comma in French). User agents are not required to support this attribute.- charoff
When present, 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
charoffis used to set the offset of an alignment character, the direction of offset is determined by the current text direction (set by thedirattribute). 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.Enumerated values: xsd:integerAn explicit offset
xsd:string(Pattern: “[0–9]+%”)A percentage offset
- class
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 whitespace characters.

- span
An attribute whose value must be an integer > 0, and that specifies the number of columns “spanned” by the

valignattribute has this value should have their textual data positioned so that the first text line occurs on a baseline common to all cells in the row. This constraint does not apply to subsequent text lines in these cells.- width
Specifies a default width for each column spanned by the current
colelement. It has the same meaning as thewidthattribute for thecolgroupelement and overrides it.
