How to control size of input in .input-group with .input-group-addon (Bootstrap3)?

Question

A have a form in a table, and all my field sizes are fitting well. But I have one datefield that has an .input-group-addon, an that is making the size control not work very well. Is there a way to fix it?

I tried some ways to make a smaller input, but the addon stopped being attached: http://jsfiddle.net/93MpC/1/

The code from Fiddle:

<div class="table-responsive">
<table class="table table-bordered">
    <tr class="form-group">
    <td><label class="field-label required-field">Name:</label></td>
    <td><div class="input-group">
        <input type="text" name="name" required id="id_name" class="form-control">
    </div></td>
    </tr>
    <tr class="form-group">
    <td><label class="field-label">Birthdate:</label></td>
    <td><div class="input-group">
        <input class="form-control datefield" id="id_dataNasc" name="dataNasc" type="text"><span class="input-group-addon"><span class="glyphicon glyphicon-calendar"></span></span>
    </div></td>
    </tr>
    <tr class="form-group">
    <td><label class="field-label">Birthdate:</label></td>
    <td><div class="input-group"><div class="row">
        <div class="col-lg-2"><input class="form-control datefield" id="id_dataNasc" name="dataNasc" type="text"></div>
        <span class="input-group-addon"><span class="glyphicon glyphicon-calendar"></span></span></div>
    </div></td>
    </tr>
    <tr class="form-group">
        <td><label class="field-label">Birthdate:</label></td>
        <td><div class="input-group">
        <div class="row">
          <div class="col-lg-3">
            <div class="col-lg-2"><input class="form-control datefield" id="id_dataNasc" name="dataNasc" type="text"></div>
            <div class="col-lg-1"><span class="input-group-addon"><span class="glyphicon glyphicon-calendar"></span></span></div>
            </div>
          </div>
        </div></td>
    </tr>
</table>
</div>

Thanks in advance!

Taken from your code, I added a class half to the parent div. Here's the css:

.half {
  width: 50%;
}

And the HTML (almost the same):

<div class="input-group half"><!-- here is .half -->
  <input class="form-control datefield" id="id_dataNasc" name="dataNasc" type="text"/>
  <span class="input-group-addon">
    <span class="glyphicon glyphicon-calendar"></span>
  </span>
</div>

Edit Or if you want to use col here's a different option:

<div class="row">
  <div class="col-md-3">
    <div class="row">
      <div class="col-md-3">Birthdate:</div>
      <div class="col-md-9">
        <div class="input-group">
          <input class="form-control datefield" id="id_dataNasc" name="dataNasc" type="text"/>
          <span class="input-group-addon">
            <span class="glyphicon glyphicon-calendar"></span>
          </span>
        </div>
      </div>
    </div>
  </div>
</div>

The proper HTML for this requires another level of nesting. More information can be found in the input groups documentation.

The <td> with your sized input and addon should look like this:

<td class="row">
    <div class="col-md-6">
        <div class="input-group">
            <input type="text" class="form-control">
            <span class="input-group-addon">
                <span class="glyphicon glyphicon-calendar"></span>
            </span>
        </div>
    </div>
</td>

The .col-* classes add padding left and right, so if that's a problem you can remove it with a little bit of CSS.
