jsf - How to display vertical and horizontal headers in p:datatable? -


i'm trying display table has both vertical , horizontal headers jsf 2.1.7 , primefaces 3.3.1.

this do:

<table>     <thead>         <tr>             <th></th>             <th>hor 1</th>             <th>hor 2</th>         </tr>     </thead>     <tbody>          <tr>             <th>vert 1</th>             <td>row 1, cell 1</td>             <td>row 1, cell 2</td>         </tr>         <tr>             <th>vert 2</th>             <td>row 2, cell 1</td>             <td>row 2, cell 2</td>         </tr>     </tbody> </table>

this best managed achieve:

<p:datatable value="#{ctrl.values}" var="val">     <p:column styleclass="ui-state-default">         <h:outputtext value="vertical header" />     </p:column>     <p:column headertext="horizontal header">         <h:outputtext value="#{val.anything}"/>     </p:column> </p:datatable>

the ui class styles cell header, that's enough me (no row selecting or filtering). i've still got problem: header text should replace "vertical header" in example comes resource bundle that's accessed through el. how can define values displayed each row?

can point me right direction? thanks.

there "standard" way of adding headers (and footers) data tables , columns in jsf. works standard , primefaces components. have add facet name header (or footer) p:datatable or p:column - depending if want have header (or footer) table or column.

with primefaces simpler columns. add attribute headertext (or footertext on p:column.

see following example:

<p:datatable var="person" value="#{bean.persons}">     <f:facet name="header">       persons     </f:facet>     <p:column>       <f:facet name="header">         name     </f:facet>       <h:outputtext value="#{person.name}"/>   </p:column>   <p:column headertext="email">       <h:outputtext value="#{person.email}"/>   </p:column> </p:datatable>

but, not know if possible add "headers" rows.

please see primefaces showcase or primefaces 3.3 user guide further details.

if need different texts coming resource bundle in every row, load texts in java code , add them objects displayed in data table. create new class extends/delgates to/proxies original class intended display , add property headerlabel (value coming resource bundle). can this: 

<p:datatable var="person" value="#{bean.personswithlabels}">     <p:column>       <h:outputtext value="#{person.headerlabel}"/>   </p:column>   ... </p:datatable>

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
