gerador de tabelas html com php

[altwes 0]

o objetivo dessa tabela é simples, quando coloco as informações na textarea a mesma deve aparecer e quando não preencho as celulas dessa tabela tambem não devem aparecer, bom até ai esta tudo ocorrendo certo, porém essa tabela tem q ser zebrada e quando eu deixo de colocar uma das informações as cores se repetem e não ficam zebradas (isso ocorre porque nem sempre vou colocar todas as informações da text area).
