Html 带有 3 列的表。固定中心列宽度。如何在其他两列上共享宽度？

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

提问by Valamas

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?

我有一个 100% 宽度的表格，有 3 列。中心列的宽度必须为 600 像素。如何在用完剩余空间的同时让另外两个宽度相等？

<table style="width: 100%">
    <tr>
        <td>left</td>
        <td style="width: 600px">center</td>
        <td>right</td>
    </tr>
</table>

Currently, depending on the content of left or right columns, they are always uneven. I have tried setting 50% width on the left and right as well as other numbers and min-width trials.

目前，根据左栏或右栏的内容，它们总是不均匀的。我尝试在左侧和右侧设置 50% 的宽度以及其他数字和最小宽度试验。

New answer to this old question.

这个老问题的新答案。

1. Give the middle column tha max-widthand min-widthinstead of width
2. Give the left and right tha widthof 50%.
3. Don't give the tablea widthat all.

1. 给中间一列th一个max-widthandmin-width而不是width
2. 给左，右th一个width的50%。
3. 根本不要给tablea width。

I have fixed this examples middle column widthat 300px.

我已将此示例中间列固定width在300px.

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

使用“colgroup”标签可能对此有很大帮助。

<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;
}

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

我想与中心列一起使用的“align=center”可能会对您有所帮助。
