JQueryに基づいて同じ内容を持つ結合セルを実装するコード

<script type="text/javascript"> 
jQuery.fn.rowspan = function(colIdx) { //封装的一个JQuery小插件 
return this.each(function(){ 
var that; 
$(&#39;tr&#39;, this).each(function(row) { 
$(&#39;td:eq(&#39;+colIdx+&#39;)&#39;, this).filter(&#39;:visible&#39;).each(function(col) { 
if (that!=null && $(this).html() == $(that).html()) { 
rowspan = $(that).attr("rowSpan"); 
if (rowspan == undefined) { 
$(that).attr("rowSpan",1); 
rowspan = $(that).attr("rowSpan"); } 
rowspan = Number(rowspan)+1; 
$(that).attr("rowSpan",rowspan); 
$(this).hide(); 
} else { 
that = this; 
} 
}); 
}); 
}); 
} 
$(function() { 
$(“#table1″).rowspan(0);//传入的参数是对应的列数从0开始，哪一列有相同的内容就输入对应的列数值 
$(“#table1″).rowspan(2); 
}); 
</script>
