How to align button horizontally in primefaces column?
提问by Mark Estrada
I am having a layout problem in one of my primefaces UI. I basically have a table wrapped in a DIV with the code below. The last column should contain buttons that I wanted to arrange horizontally so I enclosed them in a panelGroup
我的其中一个 Primefaces UI 出现布局问题。我基本上有一个用下面的代码包裹在 DIV 中的表。最后一列应该包含我想要水平排列的按钮，所以我将它们包含在一个 panelGroup 中
<div style="overflow: auto; height: 300px;">
<p:dataTable >
<p:column headerText="Column 1">
</p:column>
.
.
<p:column headerText="Actions">
<h:panelGroup layout="span">
<p:commandButton value="Edit" icon="ui-icon-scissors" />
<p:commandButton value="Delete" icon="ui-icon-trash" />
</h:panelGroup>
</p:column>
</p:dataTable>
</div>
However, when they are rendered the buttons are arrange vertically. Viewing the HTML code I notice that the buttons are both wrapped in a div so thats why there is a newline between them.
然而，当它们被渲染时，按钮是垂直排列的。查看 HTML 代码，我注意到按钮都包裹在一个 div 中，这就是为什么它们之间有换行符的原因。

Wrap them with a <h:panelGrid/>or a <p:panelGroup/>. This will render a tablewith two table cells in the same table row (so they must be appear in the same row):
用 a<h:panelGrid/>或 a包裹它们<p:panelGroup/>。这将table在同一表格行中呈现具有两个表格单元格的a （因此它们必须出现在同一行中）：
With h:panelGrid:
与h:panelGrid：
<h:panelGrid columns="2">
<p:commandButton value="Edit" icon="ui-icon-scissors" />
<p:commandButton value="Delete" icon="ui-icon-trash" />
</h:panelGrid>
With h:panelGroup:
与h:panelGroup：
If you use h:panelGroupwithout style, styleClass or id attributes the layoutattribute has no effect and no additional html will be rendered around your buttons. Anyway, adding the style:
如果您h:panelGroup不使用style、styleClass 或 id 属性，则该layout属性无效，并且不会在您的按钮周围呈现额外的 html。无论如何，添加样式：
<h:panelGroup style="white-space: nowrap">
....
</h:panelGrid>
makes them horizontally aligned, no matter which layoutvalue you are using.
使它们水平对齐，无论layout您使用的是哪个值。
