I have an ordinary HTML table:
<table>
<tr>
<td class="first-column-style">FAT</td>
<td>...</td>
</tr>
<tr>
<td class="first-column-style">FAT</td>
<td>...</td>
</tr>
</table>
I want to apply CSS style to every table cell (td) in a particular column. Is it possible to do that without applying the class/style attribute to every table cell in that column, and without JavaScript?
2015 answer, and based on the first-child answer but MUCH cleaner.
https://developer.mozilla.org/en-US/docs/Web/CSS/%3Anth-child
td:nth-child(1) { /* first column */ }
td:nth-child(2) { /* second column */ }
td:nth-child(3) { /* third column */ }
Super clean code
Additionally to Sean Patrick Floyd's solution you can combine :first-child with the adjacent sibling selector + (also not supported by IE6):
td:first-child { /* first column */ }
td:first-child + td { /* second column */ }
td:first-child + td + td { /* third column */ }
/* etc. */
Use the <col> tag and style it following this guide. This way you only need to add a class (or inline style specification) to the <col> element instead of each <td> in the table.
Caveats:
Any row or cell styling will supersede column styling.
The <col> tag only supports styling border, background, width and visibility (and their derivatives, such as background-color).
The border declaration does not work unless the <table> has border-collapse: collapse;, and the behavior is inconsistent between browsers.
The visibility declaration does not work properly in Chrome due to a known bug.
Well for the first and last columns you can use the :first-child and :last-child pseudo class:
/* make the first cell of every row bold */
tr td:FIRST-CHILD{
font-weight:bold;
}
/* make the last cell of every row italic */
tr td:LAST-CHILD{
font-style:italic;
}
Reference:
:first-child and :last-child
The following allows you to style columns at table level, and can be used in a more general way to the previous examples, as you don't have to make assumptions about the styles applied to a given column index within the style sheet itself.
I agree that the <col> approach is best if it fits your needs, but the range of styles is very limited.
The sample styles column 1, 2, & 4 with a grey text style.
HTML
<table class="example col1-readonly col2-readonly col4-readonly">
CSS
.example.col1-readonly tr td:nth-child(1),
.example.col2-readonly tr td:nth-child(2),
.example.col3-readonly tr td:nth-child(3),
.example.col4-readonly tr td:nth-child(4) {
color:#555;
}
This is an old post.
But I had the same question.
Found this to be working:
<!DOCTYPE html>
<html>
<head>
<style>
tr:nth-child(3)>td:nth-child(2){background: red;}
</style>
</head>
<table>
<tr><td></td><td>A</td><td>B</td><td>C</td></tr>
<tr><td>1</td><td>A1</td><td>B1</td><td>C1</td></tr>
<tr><td>2</td><td>A2</td><td>B2</td><td>C2</td></tr>
<tr><td>3</td><td>A3</td><td>B3</td><td>C3</td></tr>
</table>
</html>
This style setting sets the background color to red in the third row and second column,

Sorry.. I'm just a little bit confused with other answer in SO..
I have 2 tables,
and one of them rendered inside a table. (table in table)
<table class="master">
<tr>
<td>ID</td><td>Name</td><td>Information</td>
</tr>
<tr>
<td>1</td>
<td>John</td>
<td>
<table class="detail">
<tr>
<td>ID</td><td>Order</td>
</tr>
<tr>
<td>1</td><td>CA09-WYOMING-BR</td>
</tr>
</table>
</td>
</tr>
</table>
style
<style>
table.detail{
border:1px solid red;
border-collapse: collapse;
/* etc...about 20 lines code */
}
table.detail td{
border:1px solid red;
background:red;
/* etc...about 20 lines code */
}
table.master {
border:1px solid black;
border-collapse: collapse;
}
table.master td {
border:1px solid black;
background:gray;
}
</style>
And the detail table style not rendered properly because overridden by parent table CSS.
I know there are !important tag to make child CSS style not overridden, but if the CSS style about 20 lines of code should I add '!important' tag to all of them?
?

No need for !important here... Reverse the order of your styles. Put the css for the master table before detail. The way you have it is that the css for detail is being applied first then the master css is applied overriding what was set for detailed.

Or if you don't want to move css around you can update the selectors to table.master table.detail{} and table.master table.detail td{}.
updated selector fiddle
As a general rule, I use > to avoid styling nested elements unintentionally.
.master > tr > td
{
....
}
Actually, since I always use tbody, it is more like:
.master > tbody > tr > td
I don't like surprises, so I try to be careful to write css that is very explicit on what it is styling. Sure, it is a bit slower, but I find it is insignificant to the user experience and I can get stuff done a lot quicker. Others may do it differently, of course.
I have set up the following example: http://jsfiddle.net/SXEty/
<style>
table td, th { padding: 8px; text-align: left; }
table td:nth-child(1) { color: red; }
table td { color: blue }
</style>
...
<table>
<tr><th>Name</th><th>Age</th><th>City</th></tr>
<tr><td>Bob</td><td>27</td><td>Los Angeles</td></tr>
<tr><td>Charlie</td><td>34</td><td>San Diego</td></tr>
<tr><td>Daniel</td><td>41</td><td>San Francisco</td></tr>
</table>
I'm curious why the first column is colored as red instead of blue.
In my CSS, I set every first child to color "red". But then my next line of CSS sets every element to color "blue". Wouldn't the second line of CSS (color: blue) override the previous line (color: red)? Or is it that the nth-child property has precedence? If it does have precedence, is this true for all browsers?
Because td:nth-child(1) is more specific than just td.
There's a great overview of CSS specificity with a Star Wars theme that I suggest
http://www.stuffandnonsense.co.uk/archives/css_specificity_wars.html
Because table td:nth-child(1) is a more specific selector, it will have precedence over table td even if the latter is declared later.
What's interesting is if you target a parent ID with table td, everything will turn blue - even if table td:nth-child(1) is declared later in the CSS sheet.

Is there a way I can use one category to stylize all of my table cells? I cant just use
td{
}
because I have another table on the same page that I don't want the same style on. The table I want to stylize has around 40 cells, so is there a way to collectively style them short of copy-pasting a class or id 40 times?
Put a selector on the table tag:
<table class="my-special-table">
<tr><td></td></tr>
</table>
table.my-special-table td { /*style it up!*/ }
If your table has a specific attribute such an as ID, you can reference it in CSS specifically:
<table id="myStyledTable">
<tr>
<td>...
Like so:
#myStyledTable td {
}
Use this:
#table-id td {
/* some css */
}
Or
#table-id > tr > td { /* some css */ }
in case you will have other tables within this table that shouldn't have this style applied.
You can give an id/class to that table and do :
#yourtable td { }
Either an id or a class will allow it to be individually styled as:
<table class="myclass">
or
<table id="myid">
and then
.myclass td {}
or
#myid td {}
respectively.
I have a very simple html page:
<table>
<tr><th>header1</th><th>header2</th></tr>
<tr><td>item1</td><td>item2</td></tr>
<tr><td>item3</td><td>item4</td></tr>
</table>
With some simple css:
tr {
border:1px solid blue;
}
I would expect this to put a border around the trs but it doesn't put a border around it at all. How do I get a border around the tr?
Add table { border-collapse: collapse; }.
From the CSS2 specification:
In [the border-collapse: separate model], each cell has an individual border. [...] Rows, columns, row groups, and column groups cannot have borders (i.e., user agents must ignore the border properties for those elements).
Your code works, if you want a border just on the row.
However, if you are looking to have the border everywhere, you will need to do this:
tr, td, th{
border:1px solid blue;
}
Example: http://jsfiddle.net/jasongennaro/83VjH/
Borders can be added to rows of table by adding border to <td> and <th> elements [This is basically a CSS trick to achieve (hack!) that as borders cannot be added to <tr> and <tbody> elements of table]. Add following styles to your CSS to get borders around rows or headers or table cells.
table {
border-collapse: collapse;
}
table td, table th {
border: solid white;
}
td {
border-color: red (just an example, can be as per your requirement);
}
Explanation:
border-collapse rule is added to whole table. It can have two other possible properties separate (default) and inherit. For their respective effects refer https://developer.mozilla.org/en-US/docs/Web/CSS/border-collapse
Second rule i.e. adding border property to <td> (for data cells) and <th> (for header cells) is a must. If you don't add it, borders will not show up. In this rule border-color is white, it can be some other color of your choice instead of white. Basically, this rule will activate the borders around table cells and since the color is white nothing will show up.
And finally, add the color of your choice. This rule can be more specific to apply border to one <td> or a class of <td>.
Hi guys I have a table like that?
<table>
<colgroup>
<col class="selected">
<col>
</colgroup>
<tbody>
<tr>
<td>lorem</td>
<td>lorem</td>
</tr>
</tbody>
</table>
and my styles are:
col.selected {
background-color: #f3f3f3; /*for selected column*/
}
table tbody tr:nth-of-type(2n+2){
background-color:#fafafa; /*zebra effect*/
}
all works great however the zerba style owerites col selection style. Any ideas how to avoid that so the selected column will be using style from col rather than nth child ?
The problem is that the selector for the zebra background has a higher specificity than the col selector. Either give the col selector a higher specificity, or give the tr selector a lower one (or both). If they're equal, order of rules in your CSS matters.
table colgroup col.selected {
background-color: #f3f3f3; /*for selected column*/
} /* specificity: 13 */
table tr:nth-of-type(2n+2){
background-color:#fafafa; /*zebra effect*/
} /* specificity: 12, will be overridden */
As far as I know, you can't. The best work-around may to be dynamically render some CSS that highlights the correct column. To highlight the second column of a table, for example, you could use:
table tbody tr td:nth-child(2) {
background-color:red;
}
Example here:
http://jsfiddle.net/ChrisPebble/tbLrv/
Your code looks fine other than your col in the html doesn't have a selected class applied. Could this be your problem on the actual page (I relise you've only posted a code sample).
