The only thing that occurred to me would be to use tables within tables. This will give you a rough idea:

The CSS:

table {
    border-collapse: collapse;
}
td {
    white-space: nowrap;
    padding: 0px;
}
table.whole {
   width: 100%;
   margin: 0px;
}
table.half {
   width: 50%;
   display: inline-block;
}
table.quarter {
   width: 25%;
   display: inline-block;
}
td.fill {
   width: 100%;
   border-bottom: solid 2pt black;
}

The (X)HTML:

<table class="whole">
    <tr>
        <td>
            <table class="half"><tr>
               <td>Naam</td>
               <td class="fill"></td>
            </tr></table><!--
            --><table class="quarter"><tr>
               <td>Geslacht</td>
               <td class="fill"></td>
            </tr></table><!--
            --><table class="quarter"><tr>
               <td>Leeftijd</td>
               <td class="fill"></td>
            </tr></table>        
        </td>
    </tr>
    <tr>
        <td>
            <table class="whole"><tr>
                <td>Verlangd soort werk</td>
                <td class="fill"></td>
            </tr></table>
        </td>
    </tr>
    <tr>
        <td>
            <table class="whole"><tr>
                <td>Plaatselijk adres</td>
                <td class="fill"></td>
            </tr></table>
        </td>    
    </tr>
    <tr>
        <td>
            <table class="whole"><tr>
                <td>Geboorteplaats</td>
                <td class="fill"></td>
            </tr></table>
        </td>    
    </tr>
    <tr><td>&nbsp;</td></tr>
    <tr><td>Namen van de ouders:</td></tr>
    <tr>
        <td>
            <table class="half"><tr>
                <td>Vader</td>
                <td class="fill"></td>
            </tr></table><!--
            --><table class="half"><tr>
                <td>Adres</td>
                <td class="fill"></td>
            </tr></table>
        </td>
    </tr>
    <tr>
        <td>
            <table class="half"><tr>
                <td>Moeder</td>
                <td class="fill"></td>
            </tr></table><!--
            --><table class="half"><tr>
                <td>Adres</td>
                <td class="fill"></td>
            </tr></table>
        </td>
    </tr>
    <tr>
        <td>
            <table class="half"><tr>
                <td>Beroep van vader</td>
                <td class="fill"></td>
            </tr></table><!--
            --><table class="half"><tr>
                <td>Moeder</td>
                <td class="fill"></td>
            </tr></table>
        </td>
    </tr>
    <tr>
        <td>
            <table class="half"><tr>
                <td>Geboorteplaats vader</td>
                <td class="fill"></td>
            </tr></table><!--
            --><table class="half"><tr>
                <td>Moeder</td>
                <td class="fill"></td>
            </tr></table>
        </td>
    </tr>
</table>

Here's how it looks in Firefox:



I haven't tested that in any ebook reader, and it's rather hack-ish all around. Perhaps someone will have a better idea.
