Remove space between rows and columns in a table with CSS

How to remove space between rows and columns in a table with CSS?

Add this CSS reset to your CSS code to remove the unwanted space between rows and columns:

/*  
   v2.0 | 20110126
   License: none (public domain)
*/

html, body, div, span, applet, object, iframe,
h1, h2, h3, h4, h5, h6, p, blockquote, pre,
a, abbr, acronym, address, big, cite, code,
del, dfn, em, img, ins, kbd, q, s, samp,
small, strike, strong, sub, sup, tt, var,
b, u, i, center,
dl, dt, dd, ol, ul, li,
fieldset, form, label, legend,
table, caption, tbody, tfoot, thead, tr, th, td,
article, aside, canvas, details, embed, 
figure, figcaption, footer, header, hgroup, 
menu, nav, output, ruby, section, summary,
time, mark, audio, video {
    margin: 0;
    padding: 0;
    border: 0;
    font-size: 100%;
    font: inherit;
    vertical-align: baseline;
}
/* HTML5 display-role reset for older browsers */
article, aside, details, figcaption, figure, 
footer, header, hgroup, menu, nav, section {
    display: block;
}
body {
    line-height: 1;
}
ol, ul {
    list-style: none;
}
blockquote, q {
    quotes: none;
}
blockquote:before, blockquote:after,
q:before, q:after {
    content: '';
    content: none;
}
table {
    border-collapse: collapse;
    border-spacing: 0;
}

It’ll reset the CSS effectively, getting rid of the padding and margins.

Additionally,

You also have to set cellspacing attribute on the table element for cross-browser compatibility.

The space between the table cells is controlled by the CELLSPACING attribute in the TABLE tag. By setting CELLSPACING to zero, you can remove all the space between the cells of your table.

<table cellspacing="0">

EDIT (for the sake of completeness I’m expanding this 5 years later:):

Internet Explorer 6 and Internet Explorer 7 required you to set cellspacing directly as a table attribute, otherwise the spacing wouldn’t vanish.

Internet Explorer 8 and later versions and all other versions of popular browsers – Chrome, Firefox, Opera 4+ – support the CSS property border-spacing.

So in order to make a cross-browser table cell spacing reset (supporting IE6 as a dinosaur browser), you can follow the below code sample:

table{
  border: 1px solid black;
}
table td {
  border: 1px solid black; /* Style just to show the table cell boundaries */
}


table.no-spacing {
  border-spacing:0; /* Removes the cell spacing via CSS */
  border-collapse: collapse;  /* Optional - if you don't want to have double border where cells touch */
}
<p>Default table:</p>

<table>
  <tr>
    <td>First cell</td>
    <td>Second cell</td>
  </tr>
</table>

<p>Removed spacing:</p>

<table class="no-spacing" cellspacing="0"> <!-- cellspacing 0 to support IE6 and IE7 -->
  <tr>
    <td>First cell</td>
    <td>Second cell</td>
  </tr>
</table>

How to add/remove space between images in a table using CSS?

For images in td, use this for images:

display: block;

That removes unwanted space for me.

Just adding on top of the above answer, for img in td,

body {line-height: 0;}
img {display: block; vertical-align: bottom;}

This works for most email clients, including Gmail. But not Outlook. For outlook, you need to do two steps more:

table {border-collapse: collapse;}

and set every td elements to have the same height and width as its contained images. For example,

<td width="600" height="80" style="line-height: 80px;">
    <img height="80" src="http://www.website.com/images/Nature_01.jpg" width="600" />
</td>

Summary answer:

table 
{
    border-collapse: collapse;
}

will collapse all borders separating the table columns…

or try

<table cellspacing="0" style="border-spacing: 0;">

do all cell-spacing to 0 and border spacing 0 to achieve the same.

have fun!
