I need to make a table-based layout and made my table width 550px. And then I loaded an image with original width of 550px but on browser I only have 449px. I want to make in on full width. And also I have extra space between cells.
<table style="width:550px;margin:0 auto;" cellspacing="0" cellpadding="0" border="0">
<tr style="margin:0; padding:0;">
<td style="font-size:12px; line-height: 12px; width: 100%; text-align: right; color:#5A99B1;">Click <b>here</b> for the online version</td>
</tr>
<tr>
<td style="width:100%; height:10px;" cellspacing="0" cellpadding="0">
<img style="width: 100%;" src="border-top.png" />
</td>
</tr>
<tr>
<td style="width:50%; background-color:white;">
<img src="brugadalogo.png" />
</td>
<td style="width:50%; background-color:white; text-align: right;">
<img src="msdlogo.png" />
</td>
</tr>
</table>
Your table columns are not uniformly even. You have 3 rows, the first 2 have 1 column and the last one has 2 columns. Even if you have the right percentages, it is better to have it distributed evenly. Such as have all 3 rows have or "take the space of" 2 columns.
What I mean by that is that instead of using widths, you should use colspan. Also remove the width from the image, if you want its original size, it should get it by default.
<table style="width:550px;margin:0 auto;" cellspacing="0" cellpadding="0" border="0">
<tr style="margin:0; padding:0;">
<td **colspan="2"** style="font-size:12px; line-height: 12px; text-align: right; color:#5A99B1;">Click <b>here</b> for the online version</td>
</tr>
<tr>
<td **colspan="2"** style="height:10px;" cellspacing="0" cellpadding="0">
<img src="border-top.png" />
</td>
</tr>
<tr>
<td style="background-color:white;">
<img src="brugadalogo.png" />
</td>
<td style="background-color:white; text-align: right;">
<img src="msdlogo.png" />
</td>
</tr>
</table>
Hope this solves your issue.
