Two cell values clubbed into one

Two cell values clubbed into one

I have the following cell in my HTML code,31 and 519022 should be in
different cells,following is the code where I am clearly creating two
different cells..any idea why they are getting clubbed into one cell?any
way to debug it ?is there a forced way to put it in seperate cells?
Cell --> 31519022
GerritMailBody = GerritMailBody + "<td>" + str(icount) + "</td>"
GerritMailBody = GerritMailBody + "<td>" + GerritInfo['CRId'].rstrip('\n')
+ "</td>"
