TFlexCelHtmlExport.ClassPrefix Property
Prefix to be appended to all CSS classes. For example, if you set it to "test", CSS classes will be named like ".test1234". Normally you do not need to change this property, but if you need to insert multiple Excel files in the same HTML page, you need to ensure all classes have an unique ClassPrefix.
