Table borders in CSS

I am learning CSS and wish to put a border around selected tables using the following code:

table.sidebar
{
border: 2px black;
padding: 50px

}


Something similar to this code was working OK earlier today, but now it won't. The cell padding command works, but other tags like border, width, etc., are not. I have tried disabling all other table styles in the CSS.

Any ideas? I am using MS FrontPage 2002. Also, whys is it that when I apply a style to a table, like the one above, FrontPage puts in the following HTML code:

<table class="sidebar" style="border-collapse: collapse" bordercolor="#111111" cellpadding="0" cellspacing="0">

If I go to remove it to
<table class="sidebar">
all of the formatting is lost. Seems like this is defeating the whole purpose of CSS

Thanks,

You forgot to specify the border style
table.sidebar
{
border: 2px black solid;
padding: 50px

}

alternatively you can set each attribute seprately:
table.sidebar
{
border-width: 2px;
border-color: black;
border-style: solid;
padding: 50px
}
