heatmap(tbl,xvar,yvar) creates a heatmap by aggregating the variables in the table tbl. Specify xvar and yvar as the table variables that you want to visualize. The numbers in the cells and the default colors correspond to the number of times each (x, y) pair appears together in the table.

Calculate and loop over the cell center values and call the text() function. You can use the keyword arguments horizontalalignment='center' and verticalalignment='center' to keep the text value centered around x, y. See similar questions with these tags.
