Here is another modification of the most popular answer, but with handling of variable length of text in the first column labels:
http://jsfiddle.net/ozx56n41/
Basically, I'm using the second column for creating row height, like was mentioned. But my fiddle actually works unlike most mentioned above.
HTML:
<div id="outerdiv">
<div id="innerdiv">
<table>
<tr>
<td class="headcol"><div>This is a long label</div></td>
<td class="hiddenheadcol"><div>This is a long label</div></td>
<td class="long">QWERTYUIOPASDFGHJKLZXCVBNM</td>
<td class="long">QWERTYUIOPASDFGHJKLZXCVBNM</td>
</tr>
<tr>
<td class="headcol"><div>Short label</div></td>
<td class="hiddenheadcol"><div>Short label</div></td>
<td class="long">QWERTYUIOPASDFGHJKLZXCVBNM</td>
<td class="long">QWERTYUIOPASDFGHJKLZXCVBNM</td>
</tr>
</table>
</div>
</div>
CSS:
body {
font: 16px Calibri;
}
#outerdiv {
position: absolute;
top: 0;
left: 0;
right: 0;
width: 100%;
border-top: 1px solid grey;
}
#innerdiv {
overflow-x: scroll;
margin-left: 100px;
overflow-y: visible;
padding-bottom: 1px;
}
table {
border-collapse:separate;
}
td {
margin: 0;
border: 1px solid grey;
border-top-width: 0;
border-left-width: 0px;
padding: 10px;
}
td.headcol {
/* Frozen 1st column */
position: absolute;
left: 0;
top: auto;
border-bottom-width: 1px;
padding: 0;
border-left-width: 1px;
}
td.hiddenheadcol {
/* Hidden 2nd column to create height */
max-width: 0;
visibility: hidden;
padding: 0;
}
td.headcol div {
/* Text container in the 1st column */
width: 100px;
max-width: 100px;
background: lightblue;
padding: 10px;
box-sizing: border-box;
}
td.hiddenheadcol div {
/* Text container in the 2nd column */
width: 100px;
max-width: 100px;
background: red;
padding: 10px;
}
td.long {
background:yellow;
letter-spacing:1em;
}
