Chamamos de efeito zebra o ato de alternarmos as cores de plano de fundo das linhas de uma tabela. A estiliza\u00e7\u00e3o consiste em estilizar as linhas pares de uma cor e as impares de outra cor. A principal vantagem al\u00e9m de alterar o visual da tabela, \u00e9 facilitar a compreens\u00e3o e a leitura da mesma.
\nConseguimos esse efeito facilmente com as folhas de estilos em cascata (CSS). Para isso basta atribuir uma classe nas linhas pares (ou impares) e estilizar a classe conforme sua necessidade. Uma grande desvantagem \u00e9 fazer isso em tabelas grandes.
\n
\nOutra forma de se fazer isso \u00e9 com uma linguagem de programa\u00e7\u00e3o: PHP, ASP etc.
\nNesse post vou demonstrar o efeito utilizando a biblioteca jQuery.
\nAbaixo temos a marca\u00e7\u00e3o e estiliza\u00e7\u00e3o para constru\u00e7\u00e3o de nossa tabela. Como o objetivo dessa categoria do site \u00e9 a biblioteca jQuery, n\u00e3o farei explica\u00e7\u00f5es sobre tal marca\u00e7\u00e3o e estiliza\u00e7\u00e3o.

Tabela com marca\u00e7\u00e3o e estiliza\u00e7\u00e3o<\/strong>
\n\"tabela<\/p>\n
Para criar o efeito de zebra vamos utilizar os chamados pseudosseletores :even e :odd que se destinam a selecionar ocorr\u00eancias pares e \u00edmpares respectivamente de qualquer conjunto de elementos declarados.<\/p>\n
OBS: A contagem desses pseudosseletores come\u00e7a em 0.<\/div>\n
Para nosso alvo ser mais preciso, usamos o atributo id para dar uma identifica\u00e7\u00e3o a nossa tabela (id=\u201dcurso\u201d).
\nVamos iniciar trocando a cor das linhas pares (pseudosseletore :even).
\nPara isso temos que acessar o elemento tr que est\u00e1 dentro do elemento tbody que est\u00e1 dentro do identificador cursos, ent\u00e3o escrevemos nosso script da seguinte forma.<\/p>\n
\r\n<script type="text\/javascript">\r\n$(function(){\r\n$('table#curso tbody tr:even').css('background','#FFFF99');\r\n});\r\n<\/script>\r\n<\/pre>\n
Resultado:<\/strong><\/p>\n
\"tabela
tabela efeito zebra 2<\/figcaption><\/figure>\n
Agora o que temos que fazer \u00e9 praticamente a mesma coisa para as linhas \u00edmpares, s\u00f3 trocamos o pseudosseletor para odd. Veja o script completo:<\/p>\n
\r\n<script type="text\/javascript">\r\n$(function(){\r\n\/\/troca fundo de linhas pares\r\n$('table#curso tbody tr:even').css('background','#FFFF99');\r\n\/\/troca fundo de linhas \u00edmpares\r\n$('table#curso tbody tr:odd').css('background','#FFFFCC');\r\n});\r\n<\/script>\r\n<\/pre>\n
Resultado final
\n
\"tabela
tabela efeito zebra 3<\/figcaption><\/figure>
\nPodemos tamb\u00e9m fazer o efeito zebra em colunas. Para isso basta alterar os elementos tr para td (coluna).<\/p>\n","protected":false},"excerpt":{"rendered":"
