The following MWE demonstrates the problem:






a & b \\\pause
c & d



\pause effects one row if \setbeamercovered{invisible} is used, but only one cell if \setbeamercovered{transparent=??} is used.

Is it a bug? Shouldn't it be the same?! Can I write my code to affect the entire row with both of the above?

    I don't know the details, but using \pause within a tabular environment is probably not a very good idea. Why not simply use \visible<2>{<second row>}? – jub0bs Nov 17 '13 at 13:25
  • @Jubobs "using \pause within a tabular environment is probably not a very good idea" - can you link me things you're referring to by that? Is there other environments where I shouldn't use \pause? (these would do as an answer for me) – masu Nov 17 '13 at 18:34
  • How about the explanation given here: tex.stackexchange.com/a/6352/18228. I guess in general one should avoid using \pause in environments involving arrays – Herr K. Nov 19 '13 at 22:29

Please disregard my earlier comment. \pause can be used within a tabular environment.

To uncover a table rowwise, you should use \pause, not after, but before a \\. The code is adapted from the beamer documentation itself (see subsection 23.5 Uncovering a Table Rowwise).

I don't have a satisfactory explanation for the behaviour your code displays. As pointed out in KevinC's comment, \pause seems to produce surprising results when used inside array-type environment. The beamer doc (subsection 9.1) warns about that:

This command does not work inside amsmath environments like align, since these do really wicked things.

Perhaps it is best not to use \pause in ways other than those shown in the beamer manual.



    Class & A & B & C & D           \\
    X       & 1 & 2 & 3 & 4 \pause  \\
    Y       & 3 & 4 & 5 & 6 \pause  \\
    Z       & 5 & 6 & 7 & 8

  • (+1) Altough with the \setbeamercovered{invisible} setting \pause was the same if I used it after \`. It is still (or more) broken if I use \setbeamercovered{transparent}`. – masu Nov 20 '13 at 9:30
