1、在頁(yè)面中引入風(fēng)格單定義
    <style>
    .lockheadtable {behavior:url(/oblog312/lockheadtable.htc)}
    </style>
    2、在需要鎖定行列頭的表格定義中添加語(yǔ)句“class=lockheadtable”就ok了，其他參數(shù)有
    rowheadnum=鎖定行數(shù)
    colheadnum=鎖定列數(shù)
    rowheadstyle=行表頭風(fēng)格
    colheadstyle=列表頭風(fēng)格
    rowstyle=行風(fēng)格1|行風(fēng)格2|……|行風(fēng)格n
    focusstyle=獲得鼠標(biāo)焦點(diǎn)時(shí)的風(fēng)格
    3、點(diǎn)擊行標(biāo)題時(shí)可以對(duì)數(shù)據(jù)進(jìn)行排序
    注意：
    使用本組件時(shí)，行表頭中的單元格不允許跨行
    例：
    <table class=lockheadtable rowheadnum=3 colheadnum=1 rowheadstyle=background:#f7f7f7; color:black; colheadstyle=background:#f7f7f7; color:black; rowstyle=background:#ffffff; color:black;|background:#f7f7f7; color:black; focusstyle=background:green; color:white; width=1500 border=1 cellpadding=3 cellspacing=0>

    lockheadtable.htc(組件程序)
