[AJUDA] Conflito com CSS

[Igor Bueno]

Boa noite,

Sou novo aqui no fórum e logo de cara estou pedindo ajuda.

O meu problema é o seguinte:

Tenho duas folhas de estilos:

exemplo1.css

exemplo2.css

Porém, as duas contém as mesmas classes (com estilos diferentes), por exemplo:

thead

td

th

Porém, uma das tabelas fica defeituosa, pelo conflito entre os estilos. Como faço para arrumar isso? (Desculpe pela ignorância, sou muito novo em HTML e CSS).

Segue as folhas que estão dando conflito:

exemplo1.css

table { border:none; background-color:#F3F3F3; border-collapse:collapse; margin:10px 0; font:normal 11px/20px "Lucida Sans", "Lucida Sans Unicode", Helvetica, sans-serif; }
td,th { border-collapse:collapse; border-bottom:0px solid #cacaca; padding:10px 15px; text-align:center; }
table th { border-left:0px solid #cacaca; color:#ccc;  }
table td { border-left:0px solid #cacaca; }
table td:first-child, table th:first-child { text-align:left; border-left:none; font-weight:bold; width:190px; }
.first { border-left:none; text-align:left; color:#F30;}
.first2 { border-left:none; text-align:left; }
.td2 { background:url(../images/table-head-mid.gif) repeat-x 0 0; padding-left:20px; text-align:right; font-size:12px; }
th { background:url(../images/table-head-mid.gif) repeat-x 0 0; padding-left:20px; text-align:right; font-size:12px;  }
th.lefthead { background:url(../images/table-head-left.gif) no-repeat 0 0; padding-left:20px; text-align:left; }
th.righthead { background:url(../images/table-head-right.gif) no-repeat right top; text-align:left; }
th.lefthead2 { background:url(../images/table-head-left.gif) no-repeat 0 0; padding-left:20px; text-align:left; }
table a { text-decoration:none; }
thead th { color: #309; height:5px; padding:10px 15px; font-family:Arial, Helvetica, sans-serif; font-size:18px; text-align:center; }
