css3s border radius property and border collapsecollapse dont mix how can i


Edit - Original Title: Is there an alternative way to achieve border-collapse:collapse in CSS (in order to have a collapsed, rounded corner table)?

Since it turns out that simply getting the table's borders to collapse does not solve the root problem, I have updated the title to better reflect the discussion.

I am trying to make a table with rounded corners using the CSS3 border-radius property. The table styles I'm using look something like this:

table {

Here's the problem. I also want to set the border-collapse:collapse property, and when that is set border-radius no longer works. Is there a CSS-based way I can get the same effect as border-collapse:collapse without actually using it?


I've made a simple page to demonstrate the problem here (Firefox/Safari only).

It seems that a large part of the problem is that setting the table to have rounded corners does not affect the corners of the corner td elements. If the table was all one color, this wouldn't be a problem since I could just make the top and bottom td corners rounded for the first and last row respectively. However, I am using different background colors for the table to differentiate the headings and for striping, so the inner td elements would show their rounded corners as well.

Summary of proposed solutions:

Surrounding the table with another element with round corners doesn't work because the table's square corners "bleed through."

Specifying border width to 0 doesn't collapse the table.

Bottom td corners still square after setting cellspacing to zero.

Using JavaScript instead- works by avoiding the problem.

Possible solutions:

The tables are generated in PHP, so I could just apply a different class to each of the outer th/tds and style each corner separately. I'd rather not do this, since it's not very elegant and a bit of a pain to apply to multiple tables, so please keep suggestions coming.

Possible solution 2 is to use JavaScript (jQuery, specifically) to style the corners. This solution also works, but still not quite what I'm looking for (I know I'm picky). I have two reservations:

  1. this is a very lightweight site, and I'd like to keep JavaScript to the barest minimum
  2. part of the appeal that using border-radius has for me is graceful degradation and progressive enhancement. By using border-radius for all rounded corners, I hope to have a consistently rounded site in CSS3-capable browsers and a consistently square site in others (I'm looking at you, IE).

I know that trying to do this with CSS3 today may seem needless, but I have my reasons. I would also like to point out that this problem is a result of the w3c specification, not poor CSS3 support, so any solution will still be relevant and useful when CSS3 has more widespread support.


Found this answer after running into the same problem, but found it's pretty simple: just give the table overflow:hidden

No need for a wrapping element. Granted, I don't know if this would have worked 7 years ago when the question was initially asked, but it works now.

I figured it out. You just have to use some special selectors.

Here's a working example. (Broken link)

The problem with rounding the corners of the table was that the td elements didn't also become rounded. You can solve that by doing something like this:

table tr:last-child td:first-child {
    border-bottom-left-radius: 10px;

table tr:last-child td:last-child {
    border-bottom-right-radius: 10px;

Now everything rounds properly, except that there's still the issue of border-collapse: collapse breaking everything. A workaround is to set cellspacing="0" in the html instead (thanks, Joel).

You'll probably have to put another element around the table and style that with a rounded border.

The working draft specifies that border-radius does not apply to table elements when the value of border-collapse is collapse.
