I have a table with 2 columns, one of which has word-wrap: break-word:
table {
    table-layout: fixed;
    width: 100%;
    border: 1px dotted gray;
}
table td {
    border: 1px solid blue;
}
table td:nth-child(2) {
    word-wrap: break-word;
}
<table>
    <tr>
        <td>Column1</td>
        <td>Column2Column2Column2Column2Column2Column2Column2Column2Column2Column2Column2Column2Column2Column2Column2Column2Column2Column2Column2Column2Column2Column2</td>
    </tr>
</table>
I'd like to keep the first column's width to a minimum, and the second column expanding to fit the rest of the table.
But word-wrap: break-word only works if I set table-layout: fixed and that forces all columns to have equal dimensions. How can I achieve what I want without explicitly setting a width value on the first column?
