This code doesn't seem complete, in particular the JavaScript portion begins by looking for an HTML element with the class "form-btn" but there isn't one.

Perhaps the best way to illustrate a problem on the forum is to use a Workspace to build the project, and then you can make a snapshot of your workspace and post the link to it here.

this is the rest of the html code 

<div class="form">
     <form action="mahmoud.html" method="post">

        <h1>Add Employees</h1>

        <fieldset>

             <label for="name">Employee Name</label>
             <input type="text" id="name" name="user_name" class"input1">

             <label for="age">Employee Age</label>
             <input type="text" id="age" name="user_age" class"input2">

             <label for="job-role">Employee Job role</label>
             <input type="text" id="job-role" name="user_job-role" class"input3">

             <label for="e-mail">Employee Email</label>
             <input type="email" id="e-mail" name="user_job-role" class"input4">

          </fieldset>

          <fieldset class="field">

              <legend>The Employee info</legend>
              <textarea id="bio" name="user_bio" class"input5"></textarea>

              <button type="submit" name="button" class="form-btn">submit</button>

          </fieldset>
   </div>

or you can see the whole project https://github.com/YazeedAsaad0/Table

It is not correct HTML syntax to place a div directly inside a table body. That element should be a table row (tr) instead.

The event handler can then write just the contents (th, td's) into the existing table row.

For future questions, consider porting your project into a Treehouse Workspace, which would allow you to make a snapshot and post the link to it here. That greatly simplifies replicating the issue.

Changing the button type will prevent your form from being sent back to the server, wasn't that the whole point of the form? But it also still doesn't fix the HTML syntax issue, and other browsers will still exhibit the display problem (I tested it on Chrome, and there was no improvement).

The permitted content for a <tbody> element is zero or more <tr> elements. There should be no other direct children of a <tbody> (such as a <div>). For more details, see the MDN page on <tbody>. I tested the fix I proposed previously and confirmed that it does the job.
