java - 丰富 :scrollableDataTable is generating an extra column

Question

我正在使用以下代码:

<rich:scrollableDataTable value="#{allActiveUsers}" 
                                    var="user" 
                                    rows="20"
                                    >
                         <a4j:support event="onRowClick" 
                                      action="#{editUser.prepareSelectionOfUser(user)}"
                                      reRender="editUserForm"
                                      />   

                        <f:facet name="header">
                            <h:outputText value="Active  Users" />
                        </f:facet>
                        <h:column>

                            <f:facet name="header">Username</f:facet>
                            <h:outputText value="#{user.login}" />
                        </h:column>
                        <h:column>
                            <f:facet name="header">Full Name</f:facet>
                            <h:outputText value="#{user.name}" />
                        </h:column>
                        <h:column>
                            <f:facet name="header">Email address</f:facet>
                            <h:outputText value="#{user.email}" />
                        </h:column>
                    <f:facet name="footer">
                        <rich:datascroller renderIfSinglePage="false" maxPages="5" />
                    </f:facet>

                </rich:scrollableDataTable>

问题在于它无缘无故地产生白色幽灵柱。有谁知道我怎样才能摆脱它？

提前致谢。

来自 richfaces 论坛:

This column is used to fill table space when overall width of columns is not enough to cover table space. When columns are resized, they are taking space from this extra column.

根据this thread在 richfaces 论坛上，这是设计使然的。它的发生是为了补偿滚动期间表/列大小的调整。要修复此问题，请手动设置列上的 width 属性。
