Njengoko i-CSS iphakame ekusebenziseni okudumileyo kwiindawo zewebhu, ingcamango yokuba "iitafile zibi" zibambe. Ngelishwa, abaninzi abantu abaqondi kakuhle oku kuthetha ukuba iitafile ze-HTML zimbi zonke, lonke ixesha. Akunjalo nhlobo. Inyaniso kukuba iitafile ze-HTML zimbi xa zisetyenziselwa into ngaphandle kweyona njongo yonyani, okuza kubonisa idatha ye-tabular (ispredishithi, ikhalenda, njl.). Ukuba ukwakha iwebhusayithi kwaye ube nephepha lolu hlobo lwedata yenkcazo, akufanele unganqikazi ukusebenzisa itafile ye HTML kwiphepha lakho.

Ukuba uqalise ukwakha amasayithi kwiminyaka ukususela iifayile ze-HTML zokwakheka kwehlelwa yintando, unokwenene ungaziqhelana nezixhobo ezenza iitafile ze-HTML. Omnye umbuzo abaninzi xa baqala ukukhangela i-markup table:
