It seems $templateProcessor->deleteBlock doesn't work with tables. I found an alternative solution using cloneBlock :

$templateProcessor->cloneBlock('NASCONDI_SITI', 0);

If deleteBlock (and replaceBlock) don't work with tables, it should be mentioned in the docs

I get a corrupted file whenever I use either deleteBlock or replaceBlock to delete any type of block. Ffunnily enough the cloneBlock method with an argument of '0' actually achieves the deletion without corrupting the file. That means whatever the procedure being used in that method could be applied to deleteBlock or replaceBlock.
