OK, I have this working to my own satisfaction. I created my Infopath form and removed all formatting other than the tables of course. I published the form locally (it has managed code for a SQL Conn) and then uploaded via Central Admin. I then created an aspx page in SharePoint Designer and added the XMLFormView Web Part. I published the page. Once there, I edited the page to add a Content Editor Web Part. I added it underneath my form and choose a minimal chrome setting. Finally, I added this css using the source editor. I was able to find the style classes easily using Firebug.
<style type="text/css">
input {
border: 1px #CCC solid;
}
.ms-WPBody td {
font-family: arial,helvetica,sans-serif !important;
font-size: 12px !important;
}
.ms-WPBody TABLE, .ms-TPBody TABLE {
font-size: 10px;
}
.ai_ {
font-family: arial,helvetica,sans-serif !important;
font-size: 12px !important;
}
.i_ {
border: medium none;
border-collapse: collapse;
table-layout: fixed;
word-wrap: break-word;
}
.d_ {
font-family: arial;
font-size: 12px;
}
</style>
