These demonstrative particles themselves don't have gender since they are not nouns, but they have a gender-based variety, and must pair correctly with the nouns by gender. It's similar to la and le in French. You cannot say "Vive le France"; it has t obe "la France". They are used as helpers in communicating the gender of a noun. If we say "ten stôl", it reaffirms that the noun is masculine. "tá stôl" is ungrammatical. Other words are like this. E.g. interrogative wh- words: "ktorý muž?" (which man?) "ktorá žena?" (which woman?)
