HTML Cell Alignment with nested Table

Hello Experts, I am hoping you can help with my dilemma. I have an HTML page that has two tables one table nested to the other. What I need to do is align the cell width of the second table to match with the first one. I have tried everything to get it to work with no success. Any help would be most appreciated.


<!DOCTYPE html>
  <meta http-equiv="content-type" content="text/html; charset=UTF-8">
  <meta http-equiv="X-UA-Compatible" content="IE=10">
  <meta name="viewport" content="width=device-width, initial-scale=1">

      /* Create two equal columns that floats next to each other */
      .middle {
            width: 900px;
            padding: 10px;
            border: solid;
            margin-left: auto;
            margin-right: auto;

<body  bgcolor = "#86888c" text="Black">
 <div class="middle" style="background-color:#3399ff;" >
            <b><center><font size="3">

Hi Eduardo,

Basically, it's not a good idea to it this way.

Else you need to set the same width for the TD's of both tables using classes or direct style, IMO using the percent % width will be more efficient in this case.

Working live fiddle


First don't place a form in table this is not a good practice, use DIV instead.
Also don't use inline CSS this is not a good practice, use external .css file with class.

You will see this is simpler to work and adapt the CSS and you will have uptodate code (not old fashion)...

A form is not allowed to be a child element of a table or tbody or tr.

In fact, I can't see any form inside the posted HTML, the current structure is valid and if the author wants a form then he can use it around the entire table that will not affect the correctness of the code.

You can have an entire table inside a form and you can have a form inside a table cell but you cannot have part of a table inside a form.
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.
