I'm trying to build a table of pre-filled input boxes based on some XML data. I need each column's field info to appear in the specified column position. However, column nodes without any info are absent from the XML file:

<Table>
   <Row Line="1">
     <Column Position="1">
        <Field>1-1</Field>
     </Column>
     <Column Position="2">
        <Field>1-2</Field>
     </Column>
     <Column Position="3">
        <Field>1-3</Field>
     </Column>
   </Row>
   <Row Line="2">
     <Column Position="2">
        <Field>2-2</Field>
     </Column>
   </Row>
   <Row Line="3">
     <Column Position="2">
        <Field>3-2</Field>
     </Column>
     <Column Position="3">
        <Field>3-3</Field>
     </Column>
   </Row>
</Table>

How can I create a table with the info in the correct columns? I'm a little new to XSL and I've hit my head over this for days now.
