In general, no. Table salt has additives that can make pickles cloudy, etc. Pickling/canning salt doesn't have those.

However, for Annie's salsa, it shouldn't matter, since it's a flavoring.

I agree, table salt will cloud a clear substance or a brine, and the anti-caking additives can leave a residue at the bottom of the jar, which is ugly.

However, you can't see anything in the salsa, so use whatever you have. Taste before you add too much, though, as tastes vary. You can always add more, but you can't take it out.

Subject was discussed numerous time. If you want odd flavors in your salt brines, then use table salt, which has silicon dioxide and other moisture preventers.. Obviously its not a suitable substitute for canning salt. Even for that Kosher salt is mostly pure, but measures very differently due to its granule size being much larger. Pickling salt is available from many sources fairly cheap.
