It seems like some synergy could be captured here between this issue, #111, and #116. It seems as if the way to solve the colspan and rowspan issue is by copying the element, i.e. if cell[2,3] has colspan=2, then cell[2, 4] <- cell[2, 3]. I just left a PR (#119) with the more straightforward rowspan part solved in the manner proposed. WRT colspan, currently the first column element is set to the value of the colspan element and then the others spanned by it are filled with NAs. The only issue with the solution proposed above (i.e. repetition) would then be the header whereby columns cannot have equal names. This could then be viewed as a special case, solved by #116 as proposed by @r2evans.
