如何在PrimeFaces中更改面板网格的列宽

Question

I am working with Java EE and PrimeFaces. How can I change the column width of a panel grid in PrimeFaces? Is there an example ?

Answer 1

You can qualify your columns inside the panelGrid using columnClasses. The following code sets different width and stick the cells content aligned to the top-side.

<h:panelGrid columns="2" style="width: 100%" columnClasses="forty-percent top-alignment, sixty-percent top-alignment">

.forty-percent {
     width: 40%;
}

.sixty-percent {
     width: 60%;
}

.top-alignment {
     vertical-align: top;
}

I had a similar problem and here is my solution:

<p:panelGrid style="width:100%"> # notice that I do not define columns attribute in p:panelGrid!!
    <f:facet name="header"> # header
        <p:row> # p:row and p:column are obligatory to use since we do not define columns attribute!
            <p:column colspan="2"> # here I use colspan=2, coz I have 2 columns in the body
                Title
            </p:column>
        </p:row>
    </f:facet>

    <p:row>
        <p:column style="width:150px"> # define width of a column
            Column 1 content
        </p:column>
        <p:column> # column 2 will fill the rest of the space
            Column 2 content
        </p:column>
    </p:row>

    <f:facet name="footer"> # similar as header
        <p:row>
            <p:column colspan="2">
                Footer content
            </p:column>
        </p:row>
    </f:facet>
</p:panelGrid>

So as you can see, the main difference is that you do not define columns attribute in p:panelGrid . In header and footer you have to use p:row and p:column , and in my case I also have to use colspan=2 since in body we have 2 columns.

Hope this helps ;)

Have you considered the style attribute ? Example :

<p:panelGrid columns="2" style="width: 50px">

Otherwise, for columns :

<p:column style="width:50px">
