Primefaces 10中commandButton右对齐问题求助

PrimeFaces 8版本中，表单按钮布局正常（按钮在对应网格列内靠右对齐）；升级至PrimeFaces 10后，多数组件对齐问题已修复，但commandButton无法调整至右侧。

我尝试了以下方法，均未生效：

• 给p:commandButton添加style="float:right;"
• 用<div align="right">包裹按钮
• 给网格列div添加style="text-align: right;"

当前按钮的xhtml代码如下：

<p:row>                        
  <div class = "ui-grid-col-4 TexAlCenter">
    <p:commandButton id = "CB_add" 
                     rendered = "someController.rendered()"
                     class = "cb-form Fright ResponsiveCB"
                     action = "#{someController.add()}"
                     global = "true"
                     process = "@this :F_experience"
                     update = ":PGROUP_form :PGROUP_content"
                     value = "Add"
                     icon = "icon-plus" />
  </div>
  <div class = "ui-grid-col-4 TexAlCenter">
    <p:commandButton id = "CB_update"
                     rendered = "someController.rendered()"
                     class = "cb-form Fright ResponsiveCB"
                     action = "#{someController.update()}"
                     global = "true"
                     process = "@this :F_experience"
                     update = ":PGROUP_form :PGROUP_content"
                     value = "Update"
                     icon = "icon-pencil" />
  </div>
  <div class = "ui-grid-col-4 TexAlCenter">
    <p:commandButton id = "CB_cancel"
                     class = "cb-form Fright ResponsiveCB"
                     action = "#{someController.cancel()}"
                     global = "true"
                     process = "@this"
                     update = ":PGROUP_form :PGROUP_content"
                     value = "Cancel"
                     icon = "icon-cancel">
        <p:resetInput target = "@form" />
    </p:commandButton>
  </div>
  <p:defaultCommand target="CB_add" />
  <p:defaultCommand target="CB_update" />
</p:row>

可行解决方案： #

1. 覆盖网格列的对齐样式
   移除TexAlCenter类（该类可能强制居中对齐），或添加!important提升样式优先级：

   <div class="ui-grid-col-4" style="text-align: right !important;">
   

2. 修复自定义Fright类的CSS
   确保Fright类的样式未被PrimeFaces 10的默认样式覆盖：

   .Fright {
       float: right !important;
       /* 或使用margin实现块级对齐 */
       display: block;
       margin-left: auto;
   }
   

3. 使用Flex布局实现精准对齐
   替换原网格布局为PrimeFaces Flex组件，利用Flex属性控制对齐：

   <p:flexGrid>
       <p:flexGridColumn style="display: flex; justify-content: flex-end;">
           <p:commandButton id="CB_add" ... />
       </p:flexGridColumn>
       <p:flexGridColumn style="display: flex; justify-content: flex-end;">
           <p:commandButton id="CB_update" ... />
       </p:flexGridColumn>
       <p:flexGridColumn style="display: flex; justify-content: flex-end;">
           <p:commandButton id="CB_cancel" ... />
       </p:flexGridColumn>
   </p:flexGrid>
   

4. 强制按钮为块级元素并右对齐
   直接给按钮添加行内样式，强制其在容器内靠右：

   <p:commandButton style="display: block; margin-left: auto;" ... />
