This will work for simple rendering

CSS:

.custom-column
{
    background-color: #ccc; 
}

JavaScript:

columns: [{
    dataIndex: 'name',
    renderer: function (value, meta) {
        meta.css = 'custom-column';
        return value;
    }
}]

Edit:

You can use getRowClass to apply custom CSS classes to rows during rendering.

Override this function to apply custom CSS classes to rows during rendering. This function should return the CSS class name (or empty string '' for none) that will be added to the row's wrapping div. To apply multiple class names, simply return them space-delimited within the string (e.g. 'my-class another-class').

Javascript:

columns: [{
    dataIndex: 'ID',
    ...
    tdCls: 'ID' //add table css class
}],

viewConfig: {
    getRowClass: function(record, index) {
        var gender = record.get('insured');

        if (gender === 0) {
        //male
            return 'gender-male';
        } else if (gender === 1) {
        //female
            return 'gender-female';
        } else {
        //unknown
            return 'gender-unknown';
        }
    }
}

Additional CSS:

.gender-male .ID {
    background-color: #088da5;
}
.gender-female .ID {
    background-color: #f799af;
}
.gender-unknown .ID {
    background-color: #BADA55;
}
