I have added few changes in the JS and CSS in your code. This would give you the header for each column and also will set the width of table in %

To display the form in the pop-up, you can use any jquery plugin. The best jq plugin for pop-up is jquery-lightbox-me

<html>
<head>
<script type="text/javascript">
function insertTable()
{
    var num_rows = document.getElementById('rows').value;
    var num_cols = document.getElementById('cols').value;
    var width = document.getElementById('width').value;
    var theader = "<table id='table1' width = ' "+ width +"% '>";
    var tbody = "";

    for(var j = 0; j < num_cols; j++)
    {
      theader += "<th>header col "+ (j+1) +" </th>";
    }

    for(var i = 0; i < num_rows; i++)
    {
        tbody += "<tr>";
        for(var j = 0; j < num_cols; j++)
        {
            tbody += "<td>";
            tbody += "?";
            tbody += "</td>"
        }
        tbody += "</tr><br />";
    }
    var tfooter = "</table>";
    document.getElementById('wrapper').innerHTML = theader + tbody + tfooter;
}
</script>
<style>
#table1
{
    border:solid 1px;
    border-collapse:collapse;
}

#table1 th
{
    border:solid 1px;
    border-collapse:collapse;
}

#table1 td
{
    border:solid 1px;
    vertical-align:middle;
}
</style>
</head>
<body>
<form name="tableForm">
    <label>Rows: <input type="text" name="rows" id="rows"/></label><br />
    <label>Cols: <input type="text" name="cols" id="cols"/></label><br />
    <label>Width (%): <input type="text" name="width" id="width"/></label><br />
    <button type="button" onclick="insertTable()">Create Table</button>
    <div id="wrapper"></div>
</form>
</body>
</html>

Hope this would help you.

Thanks

Question 2

I am pretty new to JavaScript and would like to use a function to insert a table into a form. So far I have the following code (working - except for the header) but am struggling with the following:

1) How can I use a prompt (popup) to ask for the needed table instead of using input fields like I have ? 2) How can I include the width (in %) here ? 3) How can I always add a table header ?

I hope someone here can help me to understand this.

My Code:

<html>
<head>
<script type="text/javascript">
    function insertTable()
    {
        var num_rows = document.getElementById('rows').value;
        var num_cols = document.getElementById('cols').value;
        var theader = "<table id='table1'><thead></thead>";
        var tbody = "";

        for(var i = 0; i < num_rows; i++)
        {
            tbody += "<tr>";
            for(var j = 0; j < num_cols; j++)
            {
                tbody += "<td>";
                tbody += "?";
                tbody += "</td>"
            }
            tbody += "</tr><br />";
        }
        var tfooter = "</table>";
        document.getElementById('wrapper').innerHTML = theader + tbody + tfooter;
    }
</script>
<style>
    #table1
    {
        border:solid 1px;
        border-collapse:collapse;
        width:100%;
    }

    #table1 td
    {
        border:solid 1px;
        vertical-align:middle;
    }
</style>
</head>
<body>
    <form name="tableForm">
        <label>Rows: <input type="text" name="rows" id="rows"/></label><br />
        <label>Cols: <input type="text" name="cols" id="cols"/></label><br />
        <label>Width (%): <input type="text" name="width" id="width"/></label><br />
        <button type="button" onclick="insertTable()">Create Table</button>
        <div id="wrapper"></div>
    </form>
</body>
</html>
