[R] Storing tableGrobs in a list

[Stats Student]

Thanks for the replies. Wasn't aware that Gmail on Android sent HTML by
default, apologies. 

Storing the tableGrob-s in a list worked but for some reason grid.arrange complains on output from gtable_combine() using lists vs individual tableGrob-s. 

# works when supplying individual tableGrobs

p1<-gtable_combine(p11,p22, along=2)
p2<-gtable_combine(p11,p22, along=2)
grid.arrange(p1,p2,ncol=2)

# breaks when supplying a list of tableGrobs, error from grid.arrange()

p1<-gtable_combine(L1,along=2)
p2<-gtable_combine(L2,along=2)

grid.arrange(p1,p2,ncol=2)

Error in gList(list(list(grobs = list(list(label = "status", x = 0.5,  : 
  only 'grobs' allowed in "gList"

Also tried, still no go 

p1<-do.call(gtable_combine, list(L1,along=2))
p2<-do.call(gtable_combine, list(L2,along=2))
