Space between td's - once again - html

Question

I've closed the last topic cause havr thought it was completely answered, but as it appear now, it isn't.
link: Space between two td or tr tags
the line-height:0; isn't very useful here, because at the original work i'm doin' it obviously with other stuff, and the thing is, this line-geight is combining all content to a very small line, except the images, i guess. I know i may do the line-height:0; to specific td and not only td, but the main point here is to get rid of the space between the td's as it was once at html 4, i think.
Hope some1 know the answer
thanks!
the ''example''
<table class="main-table-default">
<tr>
<td>
<table class="main-table-header-default">
<tr>
<td><img src="http://i1.ytimg.com/vi/OguOU5cyikI/hqdefault.jpg" border="0">
</td>
</tr>
<tr>
<td><img src="http://i1.ytimg.com/vi/OguOU5cyikI/hqdefault.jpg" border="0">
</td>
</tr>
</table>
</td>
</tr>
<tr>
<td>
</td>
</tr>
<tr>
<td>random text<br><Br>
</td>
</tr>
</table>
i've got the solution, i mean just so u'll know...
but it's very ugly.
the way i thought to solve this, is to made a line-hight 0 to a specific td, and then make an line-hight of 100% to other td's in that specific td, but it's crazy... there's must be another way to solve it. other way it's very ugly :/

Answer 1

Its always good to add reset.css at the start to get rid of unnecessary spaces. I guess you haven't done it. For the time being add the following CSS
CSS:
table, tbody, tfoot, thead, tr, th, td
{
padding: 0;
border: 0;
font-size: 100%;
font: inherit;
vertical-align: baseline;
}
table
{
border-collapse: collapse;
border-spacing: 0;
}

Make sure during the start of the development, you are including reset.css

Answer 2

Don't put any whitespace (including line breaks) before closing your TD elements.
Instead of:
<td><img src="http://i1.ytimg.com/vi/OguOU5cyikI/hqdefault.jpg" border="0">
</td>
Write:
<td><img src="http://i1.ytimg.com/vi/OguOU5cyikI/hqdefault.jpg" border="0"></td>
Alternatively, depending on your doctype, you may want to omit the closing </td> tag.
