How to embed page content in a blog post

by

I’ve built an HTML table that is posted on a page in my site, and I’d like to use that same content inside a blog post (something of an announcement of the table’s publication). The table is likely to get updated from time to time, so I’d like to have a single source for maintenance purposes.

Is there a way I can do a one-off embedding of the table’s source into the blog post, so that it is always updated when the page is updated? This isn’t expected to happen often, so I don’t want to put a lot of elbow grease into making this work.

Thanks in advance!

EDIT

SO I made a really short shortcode solution using http://wordpress.org/extend/plugins/shortcode-exec-php/

extract(shortcode_atts(array('arg' => 'default'), $atts));
$id = 2328;
$post = get_post( $id );
return apply_filters('the_content', $post->post_content );

Thanks to everyone who helped. I don’t have rep to upvote answers, but i will when I get more points.

Create a shortcode to embed the content. This will always be synchronized.

Sample code from an older project. Just updated. 🙂

function t5_embed_post( $atts )

    extract(
        shortcode_atts(
            array (
                'id'    => FALSE,
                'title' => FALSE,
                'type'  => 'page'
            ),
            $atts
        )
    );

    // Not enough input data.
    if ( ! $id and ! $title )
    {
        return;
    }

    $post = FALSE;

    if ( $id )
    {
        $post = get_post( $id );
    }
    elseif( $title )
    {
        $post = get_page_by_title( $title, OBJECT, $type );
    }

    // Nothing found.
    if ( ! $post )
    {
        return;
    }

    return apply_filters( 'the_content', $post->post_content );
}

Just make sure not to embed two posts vice versa.
