CSS - Border only inside the table

2019-01-12 15:35发布

问题:

I am trying to figure out how to add border only inside the table. When I do:

table {
    border: 0;
}
table td, table th {
    border: 1px solid black;
}

The border is around the whole table and also between table cells. What I want to achieve is to have border only inside the table around table cells (without outer border around the table).

Here is markup I'm using for tables (even though I think that is not important):

<table>
    <tr>
        <th>Heading 1</th>
        <th>Heading 2</th>
    </tr>
    <tr>
        <td>Cell (1,1)</td>
        <td>Cell (1,2)</td>
    </tr>
    <tr>
        <td>Cell (2,1)</td>
        <td>Cell (2,2)</td>
    </tr>
    <tr>
        <td>Cell (3,1)</td>
        <td>Cell (3,2)</td>
    </tr>
</table>

And here are some basic styles I apply to most of my tables:

table {
    border-collapse: collapse;
    border-spacing: 0;
}

If you are doing what I believe you are trying to do, you'll need something a little more like this:

table {
  border-collapse: collapse;
}
table td, table th {
  border: 1px solid black;
}
table tr:first-child th {
  border-top: 0;
}
table tr:last-child td {
  border-bottom: 0;
}
table tr td:first-child,
table tr th:first-child {
  border-left: 0;
}
table tr td:last-child,
table tr th:last-child {
  border-right: 0;
}

The problem is that you are setting a 'full border' around all the cells, which make it appear as if you have a border around the entire table.

Cheers.

EDIT: A little more info on those pseudo-classes can be found on quirksmode, and, as to be expected, you are pretty much S.O.L. in terms of IE support.

this works for me:

table {
    border-collapse: collapse;
    border-style: hidden;
}

table td, table th {
    border: 1px solid black;
}

view example ...

tested in FF 3.6 and Chromium 5.0, IE lacks support; from W3C:

Borders with the 'border-style' of 'hidden' take precedence over all other conflicting borders. Any border with this value suppresses all borders at this location.

Example of a very simple way for you to achieve the desired effect:

<table border="1" frame="void" rules="all">
    <tr>
        <td>1111</td>
        <td>2222</td>
        <td>3333</td>
    </tr>
    <tr>
        <td>4444</td>
        <td>5555</td>
        <td>6666</td>
    </tr>
</table>

Due to mantain compatibility with ie7, ie8 I suggest using first-child and not last-child to doing this:

table tr td{border-top:1px solid #ffffff;border-left:1px solid #ffffff;}

table tr td:first-child{border-left:0;}

table tr:first-child td{border-top:0;}

回答5:

For ordinary table markup, here's a short solution that works on all devices/browsers on BrowserStack, except IE 7 and below:

table { border-collapse: collapse; }

td + td,
th + th { border-left: 1px solid; }
tr + tr { border-top: 1px solid; }

For IE 7 support, add this:

tr + tr > td,
tr + tr > th { border-top: 1px solid; }

回答6:

this should work:

table {
 border:0;
}

table td, table th {
    border: 1px solid black;
    border-collapse: collapse;
}

edit:

i just tried it, no table border. but if i set a table border it is eliminated by the border-collapse.

this is the testfile:

<html>
<head>
<style type="text/css">
table {
    border-collapse: collapse;
    border-spacing: 0;
}


table {
    border: 0;
}
table td, table th {
    border: 1px solid black;
}


</style>
</head>
<body>
<table>
    <tr>
        <th>Heading 1</th>
        <th>Heading 2</th>
    </tr>
    <tr>
        <td>Cell (1,1)</td>
        <td>Cell (1,2)</td>
    </tr>
    <tr>
        <td>Cell (2,1)</td>
        <td>Cell (2,2)</td>
    </tr>
    <tr>
        <td>Cell (3,1)</td>
        <td>Cell (3,2)</td>
    </tr>
</table>

</body>
</html>


回答7:

that will do it all without css <TABLE BORDER=1 RULES=ALL FRAME=VOID>

code from: HTML CODE TUTORIAL



回答8:

Add the border to each cell with this:

table > tbody > tr > td { border: 1px solid rgba(255, 255, 255, 0.1); }

Remove the top border from all the cells in the first row:

table > tbody > tr:first-child > td { border-top: 0; }

Remove the left border from the cells in the first column:

table > tbody > tr > td:first-child { border-left: 0; }

Remove the right border from the cells in the last column:

table > tbody > tr > td:last-child { border-right: 0; }

Remove the bottom border from the cells in the last row:

table > tbody > tr:last-child > td { border-bottom: 0; }
