h:dataTable
h:dataTable |
|
The dataTable tag renders an HTML4 compliant table element that can be
associated with a backing bean to obtain its data as well as for event handling
purposes. The table can be customized extensively using cascading stylesheet
(CSS) classes and definitions to enhance the appearance of the table's headers,
footers, columns and rows. Common formatting techniques, such as alternating row
colors, can be accomplished quite easily with this tag. The dataTable tag
typically contains one or more column tags that define the columns of the table.
A column component is rendered as a single "td" element. For more information
about columns, see the column tag documentation. A dataTable tag can also
contain header and footer facets. These are rendered as a single "th" element in
a row at the top of the table and as a single "td" element in a row at the
bottom of the table, respectively.

Tag Attributes

The bgcolor attribute sets the background color for the table. This value can be the name or the hexadecimal value of the color.
|
| binding |
Expression
|
| |
|
The value-binding expression linking this component tag to a backing bean property.
|
| bodyrows |
Text
|
| |
|
Comma separated list of row indices for which a new "tbody" element should be started (and any previously opened one should be ended).
|
| border |
Text
|
| |

| cellspacing |
Text
|

| columnClasses |
Text
|
| |
The columnClasses attribute accepts a comma-delimited list of CSS style
classes that will be applied to the columns of the table. Style classes
for an individual column may also be defined in a space separated list.
A style class is applied to a table column as the value for the class
attribute of rendered td or th element. The algorithm used to apply the
CSS style classes to the table columns is simple. In the table rendering
process, style classes are applied to columns one at a time until (a)
there are no more columns to display or (b) there are no more style
classes to apply.
-
If (a) happens at the same time as (b), the next row in the table is
rendered.
-
If (a) happens before (b), the remaining style classes are ignored.
-
If (b) happens before (a), the remaining columns will not have style
classes.
