<style>

{
height: 100%;
margin: 0px;
padding: 0px;
}
table, th, td {
border: 1px solid black;
border-collapse: collapse;
}
.table-info
{
border-spacing: 0px;
}
</style>
<body>
<table class='table-info'>
<tr>
<th style='width:100px'>colum1</th>
<th style='width:100px'>colum2</th>
<th style='width:100px'>colum3</th>
<th style='width:100px'>colum4</th>
<th style='width:100px'>colum5</th>
