I think DC needs to chime in with his expert advice.
"Belgian candi is sugar. There is a slight difference though. Belgian candi is fructose and glucose. Table sugar is sucrose. The reason for the difference is Belgian candi has been inverted. Inverted sugar is produced by splitting sucrose into fructose and glucose. Yeast has a field day with fructose and glucose, but struggles a bit with sucrose. To break down sucrose, the yeast must first produce an invertase enzyme. Its an extra step for the yeast, but the yeast (and most organisms) can do it.
Some people report the enzyme produced by the yeast can give the beer an off flavor. Just to be safe, it would be better if you can first break your table sugar down into the monosaccharides. To break down the sucrose, you can use an enzyme (from the yeast in your wort), or you can use acid and heat."
On our end its all speculative and dependent on what others have done research on. I would like to take wort and split it two ways with table sugar and clear candi sugar to see if you can taste the difference.
