Styling Table Presets

I’m trying to add a background color to the headers of the tables.  I’ve tried adding it to the meta data, CSS code.  From our WordPress site this is the code we had to which I switched the title to perc-table-1.  What am I doing wrong?

.perc-table-1 {
.perc-table-1 {
    border-left:1px solid #a5977c;
    margin-bottom:15px;
    width: 100%;
    border-spacing:0;
    border-collapse:collapse;
}

.perc-table-1 th,
.perc-table-1 thead td {
    background:#642d7d;
    color:#fff;
    font-weight:700;
    padding:6px 15px 6px 5px;
    border-right:1px solid #a5977c;
    text-align:left
}

.perc-table-1 td {
    padding:4px 5px;
    border-bottom:1px solid #a5977c;
    border-right:1px solid #a5977c;
    vertical-align:top;
    font-size:9pt
}

.perc-table-1 tr.alt {
    background-color:#fff9ef
}

.perc-table-1 tr.odd {
    background-color:#fff
}

.perc-table-1 tr.even {
    background-color:#fff9ef
}

.perc-table-1 .header {
    /*background:#642d7d url(/Assets/Images/system/no-sort.png) no-repeat 100% 50%;*/
    cursor:pointer
}

.perc-table-1.header:hover {
    background-color:#894da3
}

.perc-table-1 .headerSortUp {
    /*background-image:url(/Assets/Images/system/asc.png)*/
}

.perc-table-1 .headerSortDown {
    /*background-image:url(/Assets/Images/system/desc.png)*/
}

.perc-table-1 .headerSortDown,.fancy-table .headerSortUp {
    background-color:#4a1f5d
}

Delete the first ‘.perc-table-1 {’ b/c there’s another one next line. 

Hi Libby,

I will bring this in as a support ticket so we can grab some examples, etc.  You will hear from me shortly.

Thanks!
