Theme Help!

I have created my first WordPress Theme from HTML (..finally!)

I want to add a space to the right hand side of my blog posts with profile information and links to other sites etc..

I am using the below code and it seems to repeat the table td where i would like to add the profile and other information?

Can anyone shed some light on a solution for this?
To see what it looks like : https://blog.melbournebridalguide.com.au/

<table style="width: 1000px; height: 150px" cellspacing="0" cellpadding="0" align="center">
<tr>
<td style="width: 740px">

<table style="width: 740px" cellspacing="0" cellpadding="0" align="center">
<tr>
<td style="width: 200px; height: 44px" background='Date.jpg'>
<h2>
<?php the_time('F jS, Y'); ?>
</h2>
</td>
<td style="width: 540px; height: 44px" background='Title.jpg'>
<h4>
" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?>
</h4>
</td>
</tr>
<tr>
<td colspan="2">

<div class="entry">
<?php the_content(); ?></div>

</td>
</tr>
<tr>
<td style="height: 44px" background='Comments.jpg'>
Posted By <?php the_author_posts_link(); ?>
</td>
<td style="height: 44px" background='Comments.jpg'>
in <p class="postmetadata"><?php _e( 'Posted in' ); ?> <?php the_category( ', ' ); ?></p>
</td>
</tr>
</table>

</td>
<td style="width: 260px">
SIDEBAR AND PROFILE TAGS HERE</td>
</tr>
</table>

Thanks
