If the observed frequency is zero in entire row or column. can Pearson chi square test be used? Or can we omit the rows/column during analysis?

suppose we have 3*2 contingency table (test of independence). if one of the row has complete zero observation, can we omit that cell and proceed analysis for 2*2 contingency? or what can we do?
