Hello Matej,
This can be achieved through the cellclassname callback function. Here is an example:
<!DOCTYPE html>
<html lang="en">
<head>
    <link rel="stylesheet" href="../../jqwidgets/styles/jqx.base.css" type="text/css" />
    <style type="text/css">
        .green
        {
            background-color: Green;
            color: White;
        }
    </style>
