JSF的outputText转义属性与<code>

Question

I have a code block like this in JSF

<div class="textile">
    <h:outputText escape="false"
        value="#{NotificationContentWFHelper.generateContent(notification)}"/>
</div>

The string generated in value tag comes from database stored as CLOB which was created in Java.

I want a particular part in this string to be shown as table in the output like below.

Item 1081 has become the new reference item.

1081              1200              12000             0                 10                1081              
1073              1000              10000             0                 10                1073              
1069              800               8000              0                 10                1069              
1079              0                 0                 0                 0                 1079              
1074              0                 0                 0                 0                 1074              

Each row in table is created using format

String.format("%-18s%-18s%-18s%-18s%-18s%-18s", rowValues);

As the output in our application doesn't use monospace fonts, I couldn't show it as table. So I tried using the <code> tag only for the tabular part. The tag was parsed but it skipped all the spaces showing

Item 1081 has become the new reference item.

1081 1200 12000 0 10 1081
1073 1000 10000 0 10 1073
1069 800 8000 0 10 1069
1079 0 0 0 0 1079
1074 0 0 0 0 1074

I further tried builder.toString().replace(' ', NON_BREAKING_SPACE); where final char NON_BREAKING_SPACE = ' '; but got this

Item 1081 has become the new reference item.

1081              1200              12000             0                 10                1081              
1073              1000              10000             0                 10                1073              
1069              800               8000              0                 10                1069              
1079              0                 0                 0                 0                 1079              
1074              0                 0                 0                 0                 1074              

Using any other tag apart from <code> doesn't parse like HTML. I tried using <samp>, <p>, <table> (with <tr> & <td>). It comes up as

Item 1081 has become the new reference item.

<samp>1081              1200              12000             0                 10                1081              
1073              1000              10000             0                 10                1073              
1069              800               8000              0                 10                1069              
1079              0                 0                 0                 0                 1079              
1074              0                 0                 0                 0                 1074              
</samp>

What am I missing here?

Note: I cannot change the XHTML code as this a very specific case where I need table. I do not want to disturb other things or put extra overhead on other 99 stuff for this 1 in 100. Any other approach by modifying java code could be suitable if it renders the desired output.

Update: As per Component to inject and interpret String with HTML code into JSF page html should be parsed as escape is false, but it does not work in my case.
