Try putting the height into one of the cells, like this:

<table class="tableContainer" cellspacing="10px">
<tr>
<td style="height:15px;">NHS Number</td>
<td>&#160;</td>

Note however, that you won't be able to make the cell smaller than the content requires it to be. In that case you would have to make the text smaller first.

Your table width is 90% which is relative to it's container.

If you squeeze the page, you are probably squeezing the table width as well. The width of the cells reduce too and the browser compensate by increasing the height.

To have the height untouched, you have to make sure the widths of the cells can hold the intented content. Fixing the table width is probably something you want to try. Or perhaps play around with the min-width of the table.

That is because the words are wrapping and are going on new lines hence stretching the TR. This should fix your problem:

overflow:hidden;

Put that in the TR styles Although it should work, why not just let it stretch o0

PS. i aint tested it so dont hate XD

最佳答案

Tables are iffy (at least, in IE) when it comes to fixing heights and not wrapping text. I think you'll find that the only solution is to put the text inside a div element, like so:

td.container > div {
width: 100%;
height: 100%;
overflow:hidden;
}
td.container {
height: 20px;
}

<table>
<tr>
<td class="container">
<div>This is a long line of text designed not to wrap
when the container becomes too small.</div>
</td>
</tr>
</table>

This way, the div's height is that of the containing cell and the text cannot grow the div, keeping the cell/row the same height no matter what the window size is.

Setting the `td` height to less than the natural height of its content

Since table cells want to be at least big enough to encase their content, if the content has no apparent height, the cells can be arbitrarily resized.

By resizing the cells, we can control the row height.

One way to do this, is to set the content with an absolute position within the relative cell, and set the height of the cell, and the left and top of the content.

table {
width: 100%;
}
td {
border: 1px solid #999;
}
.set-height td {
position: relative;
overflow: hidden;
height: 3em;
}
.set-height p {
position: absolute;
margin: 0;
top: 0;
}
/* table layout fixed */
.layout-fixed {
table-layout: fixed;
}
/* td width */
.td-width td:first-child {
width: 33%;
}

The table-layout property

The second table in the snippet above has table-layout: fixed applied, which causes cells to be given equal width, regardless of their content, within the parent.

According to caniuse.com, there are no significant compatibility issues regarding the use of table-layout as of Sept 12, 2019.

Or simply apply width to specific cells as in the third table.

These methods allow the cell containing the effectively sizeless content created by applying position: absolute to be given some arbitrary girth.

Much more simply...

I really should have thought of this from the start; we can manipulate block level table cell content in all the usual ways, and without completely destroying the content's natural size with position: absolute, we can leave the table to figure out what the width should be.

table {
width: 100%;
}
td {
border: 1px solid #999;
}
table p {
margin: 0;
}
.cap-height p {
max-height: 3em;
overflow: hidden;
}

<table><tbody>
<tr class="cap-height">
<td><p>Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

I had to do this to get the result that I wanted:

<td style="font-size:3px; float:left; height:5px; vertical-align:middle;" colspan="7"><div style="font-size:3px; height:5px; vertical-align:middle;"><b><hr></b></div></td>

It refused to work with only the cell or the div and needed both.

Putting div inside a td made it work for me.

<table width="100%">
<tr><td><div style="font-size:2px; height:2px; vertical-align:middle;">&nbsp;</div></td></tr>
