Uyini umehluko Phakathi kweT and TD HTML ithebula Amathegi?

Amathebula asele athola i-rap embi ekwakhiweni kwewebhu. Eminyakeni eminingi edlule, amatafula e-HTML asetshenziselwa ukuhlelwa, okwakusobala ukuthi akulona lokho okuhloswe ngakho. Njengoba i-CSS iphakama ekusetshenzisweni okudumile kwezakhiwo zewebhu, umqondo wokuthi "amatafula awonakele" abambe. Ngeshwa, abantu abaningi abaqondi kahle lokhu kusho ukuthi amatafula e-HTML awonakele, sonke isikhathi. Akusikho iqiniso nhlobo. Okungokoqobo ukuthi amatafula e-HTML ayalungile lapho asetshenziselwa okuthile ngaphandle kwenjongo yabo yangempela, okuzobonisa idatha yamathebhu (amaspredishithi, amakhalenda, njll). Uma wakha iwebhusayithi futhi unekhasi ngaleli datha yedatha, akufanele unganqikazi ukusebenzisa ithebula le-HTML ekhasini lakho.

Uma uqale ukwakha amasayithi eminyakeni edlule kusukela amatafula we-HTML we-layout ahluleka, kungenzeka ukuthi awukwazi ukuthi izakhi zakha amatafula e-HTML. Omunye umbuzo abaningi abanakho lapho beqala ukubheka imakethe yethebula ngu:

"Uyini umehluko phakathi kwamathebula wethebula we- ne-td> HTML?"

Uyini umaka?

Ithegi ye- , noma "ithebula lwedatha", lidala amaseli etafula ngaphakathi komugqa wetafula kutafula le-HTML. Lena ithegi ye-HTML equkethe noma iyiphi imibhalo nezithombe. Ngokuyinhloko, lena yithegi yokugqoka etafuleni lakho. Amathegi azoqukatha okuqukethwe kwetafula le-HTML.

Kuyini umaka

Ithegi , noma "ithebula lethebula", lifana ngezindlela eziningi. Ingaqukatha uhlobo olufanayo lwolwazi (nakuba ungafaki isithombe ku- ), kodwa luchaza lelo cell elithile njengesihloko setafula.

Iziphequluli eziningi zewebhu zishintsha isisindo sefonti ukuze sibe nesibindi futhi sikhulume okuqukethwe esitokisini. Yebo, ungasebenzisa izitayela ze-CSS ukwenza lezo zihlokwana zetafula, kanye nokuqukethwe kwamathegi wakho, ubheke noma iyiphi indlela ongathanda ukuba babheke ekhasini lewebhu elihunyushwe ngayo.

Kufanele Usebenzise nini & lt; th & gt; Kunokuba i & lt; td & gt ;?

Ithegi kufanele isetshenziswe uma ufuna ukuqoka okuqukethwe esitokisini njengesihloko salokho kukholomu noma umugqa. Amaseli ekhanda etafuleni atholakala phezulu etafuleni noma eceleni - ngokuyisisekelo, izihloko ezingaphezulu kwamakholomu noma izihloko ngakwesokunxele noma ekuqaleni komugqa. Lezi zihloko zisetshenziselwa ukuchaza lokho okuqukethwe ngezansi noma eceleni kwazo, ukwenza kube lula ukuthi itafula kanye nokuqukethwe kwalo kubuyekezwe futhi kusebenze ngokushesha.

Ungasebenzisi isitayela amaseli wakho. Ngenxa yokuthi iziphequluli zivame ukubonisa amangqamuzana etafuleni etafuleni, abanye abaklami bewebhu abanobuqili bangase bazame ukusebenzisa leli gama besebenzisa ithegi uma befuna ukuthi okuqukethwe kube nesibindi nokugxila. Lokhu kubi ngezizathu eziningana:

1. Awukwazi ukuthembela kuziphequluli zewebhu kuzohlala zibonisa okuqukethwe ngaleyo ndlela. Iziphequluli zesikhathi esizayo zingashintsha umbala ngokuzenzakalelayo, noma zenze izinguquko ezibonakalayo ku- okuqukethwe. Akufanele neze uthembele kuphela kuzitayela zesiphequluli esizenzakalelayo futhi akufanele nanini usebenzise isici se-HTML ngoba "sibukeka" ngokuzenzakalelayo
2. Kuyinto engafanelekile. Ama-ejenti womsebenzisi afunda umbhalo angangeza ukufometha okuzwakalayo njengokuthi "umugqa womugqa: umbhalo wakho" ukukhombisa ukuthi kuse iseli. Ukwengeza, ezinye izinhlelo zokusebenza zeWebhu ziphrinta izihloko zetafula ngaphesheya kwekhasi ngalinye, okuzoholela ezinkingeni uma i-cell engekho ngempela ikhanda kodwa isetshenziselwa izizathu zesitayela kuphela. Ngezansi, ukusebenzisa amathegi ngale ndlela kungabangela izinkinga zokufinyeleleka kubasebenzisi abaningi, ikakhulukazi labo abasebenzisa amadivaysi asekelwe ukufinyelela okuqukethwe kwakho kusayithi.
3. Kufanele usebenzise i-CSS ukuze uchaze indlela amangqamuzana abukeka ngayo.Ukuhlukaniswa kwesitayela (CSS) nokuhlela (i-HTML) bekuwumkhuba omuhle ekwakhiweni kwewebhu iminyaka eminingi. Phinda futhi, sebenzisa ngoba okuqukethwe kwaleso selesi kuyinhloko, hhayi ngoba uthanda indlela isiphequluli cishe esinganikeza ngayo lokho okuqukethwe ngokuzenzakalelayo.
