HTML and CSS Reference
colspan This attribute takes a numeric value that indicates how many columns wide a cell
should be. This is useful for creating tables with cells of different widths.
headers This attribute takes a space-separated list of id values that correspond to the
header cells related to this cell.
height This attribute indicates the height of the cell, in pixels or as a percentage. Some
browsers may have rendering problems with percentage values.
nowrap This attribute keeps the content within a table cell from automatically wrapping.
The nowrap attribute takes no value under HTML but should be set to the value nowrap
rowspan This attribute takes a numeric value that indicates how many rows high a table
cell should span. This attribute is useful in defining tables with cells of different heights.
scope This attribute specifies the table cells for which the current cell provides header
information. A value of col indicates that the cell is a header for the rest of the column
below it. A value of colgroup indicates that the cell is a header for its current column
group. A value of row indicates that the cell contains header information for the rest of the
row it is in. A value of rowgroup indicates that the cell is a header for its row group. This
attribute might be used in place of the header attribute and is useful for rendering
assistance by nonvisual browsers. This attribute was added very late to the HTML 4
specification, and support for this attribute is still minimal.
valign This attribute is used to set the vertical alignment for the table cell. The specification
defines baseline , bottom , middle , and top . Internet Explorer also supports center ,
which should be the same as middle .
width This attribute specifies the width of a cell, in pixels or as a percentage value.
