tables in FO( Formatting Object)

Hi all

I want to write an .fo (formatting objects) file which displays table and want to convert it into .pdf using FOP.

Now I have code for table (table.fo):
----------------------------------------------------------------------------------
<fo:table-and-caption text-align="center" start-indent="100pt">

<fo:table-caption start-indent="0pt" text-align="start">
<fo:block>Caption for this table
</fo:block>
</fo:table-caption>

<fo:table width="325pt" table-layout="fixed">

<fo:table-column column-width="100pt" column-number="1">
</fo:table-column>
<fo:table-column column-width="150pt" column-number="2">
</fo:table-column>
<fo:table-column column-width="75pt" column-number="3">
</fo:table-column>

<fo:table-body start-indent="0pt" text-align="start">

<fo:table-row>

<fo:table-cell>
<fo:block>Cell 1
</fo:block>
</fo:table-cell>
<fo:table-cell>
<fo:block>Cell 2
</fo:block>
</fo:table-cell>
<fo:table-cell>
<fo:block>Cell 3
</fo:block>
</fo:table-cell>

</fo:table-row>

</fo:table-body>

</fo:table>

</fo:table-and-caption>
---------------------------------------------------------------------------------
and if I use FOP for generating table.pdf it is giving error:
C:\software\fop\fop-0.20.5rc3a>fop ex/table21.fo ex/table21.pdf
[INFO] Using org.apache.xerces.parsers.SAXParser as SAX2 Parser

[Fatal Error] table21.fo:2:64: The prefix "fo" for element "fo:table-and-caption
" is not bound.
[ERROR] The prefix "fo" for element "fo:table-and-caption" is not bound.


What shall I have in table.fo file to generate proper pdf file???


Any help is appreciated.
