The parse=TRUE argument means that all the table content will be
parsed and interpreted as expression. In your content you have invalid
expressions (e.g. text with spaces), which cause the error. You could
try to reformat the labels,

# replace the spaces
m = gsub(" ","~",as.matrix(absoluteTable))
# wrap the < sign in ""
m = gsub("<","\"<\"",m)
library(gridExtra)
grid.table(data.frame(m),parse=T)

but I don't see the point of using parse in your example (there is not
plotmath expression to render).

Of course, I welcome any suggestion to create a matrix of valid
expressions, I have no clue how to deal with these.
