Tag name: <amc:column>

The immediate children of a Table component must all be <amc:column> components. Each visible Column component creates a separate column in the Table.

Use "headerText" attribute on a Column to create the column header. The following example creates a two-column table with the column headers - "Firstname" and "Lastname":

<amc:table>
  <amc:column headerText="Firstname">
    ...
  </amc:column>
  <amc:column headerText="Lastname">
    ...
  </amc:column>
</amc:table>
          

The child components of each Column display the data for each row in that column. The Column does not create child components per row; instead, each child is repeatedly rendered (stamped) once per row. Because of this stamping behavior, only certain types of components are supported as children inside a Column.

As each row is stamped, the data for the current row ( see getRowData() on the Table) is copied into an EL reachable property. The name of this property is defined by the var property on the Table. Once the Table has completed rendering, this property is removed (or reverted back to its previous value). In the following example, the data for each row is placed under the EL property "row". Each Column displays the data for each row by getting further properties from the "row" property:

<amc:table var="row" value="#{myBean.employees}">
  <amc:column>
    <amc:outputText value="#{row.firstname}"/>
  </amc:column>
  <amc:column>
    <amc:outputText value="#{row.lastname}"/>
  </amc:column>
</amc:table>
          

<amc:table var="row" value="#{periodicTable.tableData}" id="t1">
   <amc:column headerText="Element Name" sortable="true" sortProperty="name" id="column1">
      <amc:outputText value="#{row.name}" id="ot1"/>
   </amc:column>
</amc:table>
