How to add border radius on table row

Question

Does anyone know how to style tr as we like?

I\'ve used border-collapse on table, after that tr\'s can display 1px solid border I give them.

However, when I\

Answer 1

Use border-collapse:seperate; and border-spacing:0; but only use border-right and border-bottom for the tds, with border-top applied to th and border-left applied to only tr td:nth-child(1).

You can then apply border radius to the corner tds (using nth-child to find them)

<table>
  <tr>
    <th>title 1</th>
    <th>title 2</th>
    <th>title 3</th>
  </tr>
  <tr>
    <td>item 1</td>
    <td>item 2</td>
    <td>item 3</td>
  </tr>
  <tr>
    <td>item 1</td>
    <td>item 2</td>
    <td>item 3</td>
  </tr>
  <tr>
    <td>item 1</td>
    <td>item 2</td>
    <td>item 3</td>
  </tr>
  <tr>
    <td>item 1</td>
    <td>item 2</td>
    <td>item 3</td>
  </tr>
</table>

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

tr th,
tr td {
  padding: 20px;
  border-right: 1px solid #000;
  border-bottom: 1px solid #000;
}

tr th {
  border-top: 1px solid #000;
}

tr td:nth-child(1),
tr th:nth-child(1) {
  border-left: 1px solid #000;
}

/* border radius */
tr th:nth-child(1) {
  border-radius: 10px 0 0 0;
}

tr th:nth-last-child(1) {
  border-radius: 0 10px 0 0;
}

tr:nth-last-child(1) td:nth-child(1) {
  border-radius: 0 0 0 10px;
}

tr:nth-last-child(1) td:nth-last-child(1) {
  border-radius: 0 0 10px 0;
}

Answer 2

You can only apply border-radius to td, not tr or table. I've gotten around this for rounded corner tables by using these styles:

table { border-collapse: separate; }
td { border: solid 1px #000; }
tr:first-child td:first-child { border-top-left-radius: 10px; }
tr:first-child td:last-child { border-top-right-radius: 10px; }
tr:last-child td:first-child { border-bottom-left-radius: 10px; }
tr:last-child td:last-child { border-bottom-right-radius: 10px; }

Be sure to provide all the vendor prefixes. Here's an example of it in action.

Actual Spacing Between Rows

This is an old thread, but I noticed reading the comments from the OP on other answers that the original goal was apparently to have border-radius on the rows, and gaps between the rows. It does not appear that the current solutions exactly do that. theazureshadow's answer is headed in the right direction, but seems to need a bit more.

For those interested in such, here is a fiddle that does separate the rows and applies the radius to each row. (NOTE: Firefox currently has a bug in displaying/clipping background-color at the border radii.)

The code is as follows (and as theazureshadow noted, for earlier browser support, the various vendor prefixes for border-radius need added).

table { 
    border-collapse: separate; 
    border-spacing: 0 10px; 
    margin-top: -10px; /* correct offset on first border spacing if desired */
}
td {
    border: solid 1px #000;
    border-style: solid none;
    padding: 10px;
    background-color: cyan;
}
td:first-child {
    border-left-style: solid;
    border-top-left-radius: 10px; 
    border-bottom-left-radius: 10px;
}
td:last-child {
    border-right-style: solid;
    border-bottom-right-radius: 10px; 
    border-top-right-radius: 10px; 
}

Answer 4

I think collapsing your borders is the wrong thing to do in this case. Collapsing them basically means that the border between two neighboring cells becomes shared. This means it's unclear as to which direction it should curve given a radius.

Instead, you can give a border radius to the two lefthand corners of the first TD and the two righthand corners of the last one. You can use first-child and last-child selectors as suggested by theazureshadow, but these may be poorly supported by older versions of IE. It might be easier to just define classes, such as .first-column and .last-column to serve this purpose.

Answer 5

Not trying to take any credits here, all credit goes to @theazureshadow for his reply, but I personally had to adapt it for a table that has some <th> instead of <td> for it's first row's cells.

I'm just posting the modified version here in case some of you want to use @theazureshadow's solution, but like me, have some <th> in the first <tr>. The class "reportTable" only have to be applied to the table itself.:

table.reportTable {
    border-collapse: separate;
    border-spacing: 0;
}

table.reportTable td {
    border: solid gray 1px;
    border-style: solid none none solid;
    padding: 10px;
}

table.reportTable td:last-child {
    border-right: solid gray 1px;
}

table.reportTable tr:last-child td{
    border-bottom: solid gray 1px;
}

table.reportTable th{
    border: solid gray 1px;
    border-style: solid none none solid;
    padding: 10px;
}

table.reportTable th:last-child{
    border-right: solid gray 1px;
    border-top-right-radius: 10px;
}

table.reportTable th:first-child{
    border-top-left-radius: 10px;
}

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

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

Feel free to adjust the paddings, radiuses, etc to fit your needs. Hope that helps people!

All the answers are way too long. The easiest way to add border radius to a table element that accepts border as a property, is doing border radius with overflow: hidden.

border: xStyle xColor xSize;
border-collapse: collapse;
border-radius: 1em;
overflow: hidden;
