I am trying to set the table width to 100% for above table but it has no effect it goes beyond window width. how do i change the width of table so it is same size as window.

Solution

The problem is, the content inside your table requires more space than 100% of your window-size offers.

What you could do, is to use the overflow-property of CSS. Try the following example and chose, wether this is an option for you:

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<style>
    .table {
        color: green;
        display: block;
        max-width: 100%;
        overflow: scroll; <!-- Available options: visible, hidden, scroll, auto -->
    }
</style>
</head>
<body>

<table border="1" class="table">

    <tr>
        <td>aaaaaaaaaaaaaaaaaaaaaaaaaaaaa</td>
        <td>aaaaaaaaaaaaaaaaaaaaaaaaaaaaa</td>
        <td>aaaaaaaaaaaaaaaaaaaaaaaaaaaaa</td>
        <td>aaaaaaaaaaaaaaaaaaaaaaaaaaaaa</td>
        <td>aaaaaaaaaaaaaaaaaaaaaaaaaaaaa</td>
        <td>aaaaaaaaaaaaaaaaaaaaaaaaaaaaa</td>
        <td>aaaaaaaaaaaaaaaaaaaaaaaaaaaaa</td>
        <td>aaaaaaaaaaaaaaaaaaaaaaaaaaaaa</td>
        <td>aaaaaaaaaaaaaaaaaaaaaaaaaaaaa</td>
        <td>aaaaaaaaaaaaaaaaaaaaaaaaaaaaa</td>
        <td>aaaaaaaaaaaaaaaaaaaaaaaaaaaaa</td>
        <td>aaaaaaaaaaaaaaaaaaaaaaaaaaaaa</td>
        <td>aaaaaaaaaaaaaaaaaaaaaaaaaaaaa</td>
        <td>aaaaaaaaaaaaaaaaaaaaaaaaaaaaa</td>
    </tr>


</table>
</body>
</html>

There are 4 options available for the overflow-property: visible, hidden, scroll and auto. The above example illustrates the scroll-option, which adds a scroll-bar to the table itself.
