If you want to change one of your custom table formats, you just overwrite it by saving the new format under the same name as the previous version.
If you want to delete a custom table format, select this format from the “Table menu”, activate the “Table menu field” by clicking it once while pressing the “Option” key, and then hit the “Backspace” key. The effect of this is that the “Table menu field” becomes empty. Finally hit the “Enter” key to complete the operation. As a result your custom table format is removed from the “Table menu”.
Note that DynRisk does not allow the factory made table format to be deleted.
