Table with 3 columns. Fixed center column width. How to have shared width on other two columns?

Question

i have a 100% width table with 3 columns. The center column must be 600px width. How can I have the other two equal width while using up the remaining space?

Answer 1

The use of "colgroup" tag could be a great help for this.

<table class="fixed-center-table" border="1">
        <thead>
            <colgroup>
                <col>
                <col id="middle-column">
                <col>
            </colgroup>
            <tr>
                <th>First Column</th>
                <th></th>
                <th>Third Column</th>
            </tr>
        </thead>

        <tbody>
            <tr>
                <td>AAAAAA</td>
                <td>BBBB</td>
                <td>CCCCC</td>
            </tr>
            <tr>
                <td>AAAAAA</td>
                <td>BBBB</td>
                <td>CCCCC</td>
            </tr>
            <tr>
                <td>AAAAAA</td>
                <td>BBBB</td>
                <td>CCCCC</td>
            </tr>
        </tbody>
</table>

.fixed-center-table {
    table-layout: fixed;
    width: 100%;
    border-collapse: collapse;
}

.fixed-center-table  td{
   text-align: center;
}

col#middle-column {
   width: 600px;
}

Answer 2

I guess "align=center" used with center column may help you.

Answer 3

New answer to this old question.

1. Give the middle column th a max-width and min-width instead of width
2. Give the left and right th a width of 50%.
3. Don't give the table a width at all.

I have fixed this examples middle column width at 300px.

jsBin Example!

CSS

table {
    border-collapse: collapse;
}
th, td {
    border: solid 1px #CCC;
    padding: 10px;
}
.fixed {
    max-width: 300px;
    min-width: 300px;
}
.fluid {
        width: 50%;
}

HTML

<table>
    <thead>
        <tr>
            <th class="fluid">First Column</th>
            <th class="fixed">Fixed Column</th>
            <th class="fluid">Third Column</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td></td>
            <td></td>
            <td></td>
        </tr>
    </tbody>
