Those are indeed nice-looking tables for certain scenarios. But I think for the particular type of information that I am presenting -- namely, a truth table -- that the cell walls are necessary to logically divide the information. Later in my presentation I present a Sudoku grid, and I would like ...

Thank you Stefan! That has the progressive introduction effect that I am going for. Unfortunately there are issues with the walls between the cells also being invisible until the corresponding elements are introduced. For example, in the following MWE, the horizontal line atop the bottom row, as ...

Hi there,

Sorry to intrude, but I have a very similar question. You say that the tables can be uncovered piecewise, and then list the two methods given in the manual, namely row-wise and column-wise. Suppose I have a 3x3 table, and I want the elements in cells (1,1), (1,2), (1,3), (2,1), and (3,1 ...
