Hi,
You can break the word but I don’t think any current browser will hyphenate them properly.
e.g.
<!DOCTYPE HTML>
<html>
<head>
<meta charset="utf-8">
<title>Untitled Document</title>
<style>
.nowrap {
-ms-word-break: break-all;
word-break: break-all;
word-break: break-word;
-webkit-hyphens: auto;
-moz-hyphens: auto;
hyphens: auto;
}
table {
width:200px;
margin:20px;
border:1px solid #000;
}
.test1 {
table-layout:fixed;
}
</style>
</head>
<body>
<table class="test1 nowrap">
<tr>
<td>thisisatestthisisatestthisisatestthisisatestthisisatestthisisatestthisisatestthisisatest</td>
</tr>
</table>
<table class="test2 nowrap">
<tr>
<td>thisisatestthisisatestthisisatestthisisatestthisisatestthisisatestthisisatestthisisatest</td>
</tr>
</table>
</body>
</html>
If your cells are getting that small that they need hyphenation then you should think about using media queries and creating a linear display instead for smaller screens.
e.g.
<!DOCTYPE HTML>
<html>
<head>
<meta charset="utf-8">
<title>Untitled Document</title>
<style>
.mytable{
width:100%;
margin:0 auto;
max-width:960px;
border-collapse:collapse;
}
.mytable td{
border:1px solid #000;
padding:10px;
vertical-align:top;
}
p{margin:0 0 1em}
@media screen and (max-width:601px) {
table.mobile-optimised {
word-wrap:break-word;
}
table.mobile-optimised thead {
display:none
}
table.mobile-optimised td {
display:block;
float:left;/* ie9 and under hack */
width:100%;
clear:both;
background:#f5f5f5;
padding:10px 5px;
-moz-box-sizing:border-box;
-webkit-box-sizing:border-box;
box-sizing:border-box;
}
table.mobile-optimised tbody, table.mobile-optimised tr {
display:block
}
.mobile-optimised td:before {
content:attr(data-th);
display:block;
font-weight:bold;
margin:0 0 2px;
color:#000;
}
.mobile-optimised tbody tr {
border-bottom:1px solid #00c0f3
}
}
</style>
</head>
<body>
<table class="mytable mobile-optimised" >
