Document

Gets the toString of an Object returning an empty string ("") if null input.

 ObjectUtils.toString(null)         = "" ObjectUtils.toString("")           = "" ObjectUtils.toString("bat")        = "bat" ObjectUtils.toString(Boolean.TRUE) = "true"

 * @throws Exception if an error is encountered while writing the table body.
