Answer 1

Remove display: block in .Table-Normal
Fiddle
.Table-Normal {
position: relative;
//display: block;
margin: 10px auto;
padding: 0;
width: 100%;
height: auto;
border-collapse: collapse;
text-align: center;
}

Answer 2

By specifying display: block you've overriding the default value from the browser stylesheet for the table element: display: table. Removing display: block or replacing it with display: table fixes this.

Answer 3

As people have mentioned you have to remove display:block; for this to work. If you need to keep scrolling functionality wrap the table inside a div and set overflow rules on that
<div class = "table-container">
<table>...</table>
</div>
.table-container{
height:100px
width:100px
overflow-x:scroll;
table{
display: table;
width:100%;
}
}
