If I have a table with two columns, how do I specify a padding or any other css so that it is applied just for the first column of <td>s. Also how do I style an n-th column similarly?

You could use the n-th child selector.

to target the nth element you could then use:

td:nth-child(n) {  
  /* your stuff here */
}

(where n starts at 1)

    Suggest td:first-child over this mostly because it has more support for older IE versions. If browser support isn't an issue nth-child is a powerful selector to begin using. – lukek Mar 28 '13 at 06:05

    Yes, for the first element, `first-child` is better. But OP asked for both :) – RRikesh Mar 28 '13 at 06:08

    And `n` start with 1, not with 0. – robsch Oct 28 '15 at 15:56

If you've to support IE7, a more compatible solution is:

/* only the cells with no cell before (aka the first one) */
td {
    padding-left: 20px;
}
/* only the cells with at least one cell before (aka all except the first one) */
td + td {
    padding-left: 0;
}

Also works fine with li; general sibling selector ~ may be more suitable with mixed elements like a heading h1 followed by paragraphs AND a subheading and then again other paragraphs.

The :nth-child() and :nth-of-type() pseudo-classes allows you to select elements with a formula.

The syntax is :nth-child(an+b), where you replace a and b by numbers of your choice.

For instance, :nth-child(3n+1) selects the 1st, 4th, 7th etc. child.

td:nth-child(3n+1) {  
  /* your stuff here */
}

:nth-of-type() works the same, except that it only considers element of the given type ( in the example).

This should help. Its CSS3 :first-child where you should say that the first tr of the table you would like to style. http://reference.sitepoint.com/css/pseudoclass-firstchild

To select the first column of a table you can use this syntax

tr td:nth-child(1n + 2){
  padding-left: 10px;
}
