Renders an HTML "table" element compliant with the HTML 401 specification. Render the "caption" facet, if present, inside a "caption" element immediately below the "table" element. If the "captionClass" attribute is specified, render its value as the value of the "class" attribute on the "caption" element. If the "captionStyle" attribute is specified, render its value as the value of the "style" attribute on the "caption" element.
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.
Column Groups
If the UIData component has a "colgroups" facet, render its contents. Consistent with the rules of facets in general, this facet must have only one child. In general, this will be a panel group component that will contain colgroup and col elements per the HTML Table specification. Use of column grouping can improve accessibility. This facet must be rendered before the table header and footer.
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 the UIData 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 each UIColumn 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 UIColumn component, if present, as the value of the "class" attribute on the "th". If the "headerClass" attribute of the UIColumn component is not present, 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 "scope" attribute on the "th" element.
Close out the "thead" element.
Rendering the footer
If the UIData component has a "footer" facet, or any of the child UIColumn components has a "footer" facet, render a "tfoot" element. If the UIData component has "footer" facets, encode the contents inside of a "tr" element.
If any of the child UIColumn components has a "footer" facet render a "td" element. For each UIColumn that actually has a "footer" facet, render it inside of a "td" element. Columns that don't have a "footer" facet cause an empty "td" element to be rendered. Output the value of the "footerClass" attribute of the UIColumn component, if present, as the value of the "class" attribute on the "td". If the "footerClass" attribute of the UIColumn component is not present, output the value of the "footerClass" attribute of the UIData component, if present, as the value of the "class" attribute on the "td".
If the UIData component has a "footer" facet, encode its contents inside of "tr" and "td" elements, respectively. Output the value of the "footerClass" attribute of the UIData component, if present, as the value of the "class" attribute on the "td". Output the number of child UIColumn components of the UIData component as the value of the "colspan" attribute on the "td".
Close out the "tfoot" element.
Rendering the table body
Look at the value of the "bodyrows" attribute. If present, this must be a comma separated list of integers. Each entry in this list is the row index of the row before which a "tbody" element should be rendered.
If there was no "bodyrows" attribute, or it was empty, 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. If the current row index is contained in the "bodyrows" attribute, check if a "tbody" start element was rendered that needs to be closed, and if so, close the "tbody" element. Then render a "tbody" element start. Otherwise, do not render a "tbody" element.
Output a "tr" element. Output the value of the "rowClasses" per the attribute description below. For each UIColumn child, if the column component has a "rowHeader" attribute with a value of "true", output a "th" element with a "scope" attribute with the value of "row". Otherwise, if the column component has no "rowHeader" attribute, or its value is false, output a "td" element. In either case attach 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" or "th" 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.
