Renders an HTML "table" element compliant with the HTML 401
specification. Please consult the javadoc for UIData
to supplement this specification. If the "styleClass" attribute
is specified, render its value as the value of the "class"
attribute on the "table" element. Any pass-through attributes are
also rendered on the "table" element.
Rendering the header
If the UIData
component has a "header" facet, or
any of the child UIColumn
components has a "header"
facet, render a "thead" element. If the UIData
component has a "header" facet, encode its contents inside of "tr"
and "th" elements, respectively. Output the value of the
"headerClass" attribute of the UIData
component, if
present, as the value of the "class" attribute on the "th".
Output the number of child UIColumn
components of theUIData
component as the value of the "colspan"
attribute on the "th". Output "colgroup" as the value of the
"scope" attribute on the "th" element.
If any of the child UIColumn
components has a
"header" facet render a "tr" element. For eachUIColumn
that actually has a "header" facet, render
it inside of a "th" element. Columns that don't have a "header"
facet cause an empty "th" element to be rendered. Output the
value of the "headerClass" attribute of the UIData
component, if present, as the value of the "class" attribute on
the "th". Output "col" as the value of the "colgroup" attribute
on the "th" element.
Close out the "thead" element.
Rendering the footer
Follow the same process as for the header, except replace "header" with "footer", "th" with "td", "thead" with "tfoot", and "headerClass" with "footerClass". Do not render any "scope" attribute for the footer.
Rendering the table body
Render a "tbody" element. Keep track of the result of the
"rows" property on the UIData
component. Keep track
of the number of rows we have rendered so far. Iterate through
the rows. Set the "rowIndex" property of the UIData
component to be correct as we iterate through the rows. Stop
rendering children and close out the "tbody" element if the
"rowAvailable" property of the UIData
returned false.
Output a "tr" element. Output the value of the "rowClasses" per
the attribute description below. For each UIColumn
child, output a "td" element, attaching the value of the
"columnClasses" attribute of the UIData
component per
the attribute description below. Recursively encode each child of
each UIColumn
child. Close out the "td" element.
When done with the row, close out the "tr" element. When done
with all the rows, close out the "tbody" element.
When done rendering all the rows, set the "rowIndex" property of
the UIData
to -1, and close out the "table"
element.

first | false | false | java.lang.String | Zero-relative row number of the first row to be displayed. If this property is set to zero, rendering will begin with the first row of the underlying data. |
id | false | false | java.lang.String | The component identifier for this component. This value must be unique within the closest parent component that is a naming container. |
rendered | false | false | java.lang.String | Flag indicating whether or not this component should be rendered (during Render Response Phase), or processed on any subsequent form submit. |
rows | false | false | java.lang.String | The number of rows to display, starting with the one identified by the "first" property. If this value is set to zero, all available rows in the underlying data model will be displayed. |
value | false | false | java.lang.String | The current value of this component. |
var | false | false | java.lang.String | Name of a request-scope attribute under which the model data for the row selected by the current value of the "rowIndex" property (i.e. also the current value of the "rowData" property) will be exposed. |
bgcolor | false | false | java.lang.String | Name or code of the background color for this table. |
border | false | false | java.lang.String | Width (in pixels) of the border to be drawn around this table. |
cellpadding | false | false | java.lang.String | Definition of how much space the user agent should leave between the border of each cell and its contents. |
cellspacing | false | false | java.lang.String | Definition of how much space the user agent should leave between the left side of the table and the leftmost column, the top of the table and the top of the top side of the topmost row, and so on for the right and bottom of the table.

columnClasses | false | false | java.lang.String | Comma-delimited list of CSS style classes that will be applied to the columns of this table. A space separated list of classes may also be specified for any individual column. If the number of elements in this list is less than the number of columns specified in the "columns" attribute, no "class" attribute is output for each column greater than the number of elements in the list. If the number of elements in the list is greater than the number of columns specified in the "columns" attribute, the elements at the posisiton in the list after the value of the "columns" attribute are ignored. |
