tablescrollbar&headerfixed
有很多页面由于数据量过大，会产生横纵滚动条。为了便于使用者观看，我们要把表头固定一下。根据这个需求写了个demo来实现这个功能。
主要解决了几点问题：
1.table实现横纵滚动条
2.table表头固定
3.table列宽自适应
4.table内容不换行
主要代码块
css：
.table-scroll{
width:calc(100%-5px);
overflow-x:scroll;
white-space:nowrap;
}
.table-scrolltable{
table-layout:fixed;
width:calc(100%-10px);
background-color:darkseagreen;
}
.table-scrollthead{
display:table-row;
background-color:bisque;
}
.table-scrolltbody{
overflow-y:scroll;
overflow-x:hidden;
display:block;
height:calc(100vh-300px);
}
.table-scrollth,td{
width:160px;
overflow:hidden;
text-overflow:ellipsis;
min-width:160px;
border:1pxsolid#808080;
}
h4,h5{
color:cornflowerblue;
}
js：
$(function(){
$('.table-scroll').scroll(function(){
$('.table-scrolltable').width($('.table-scroll').width()
+$('.table-scroll').scrollLeft());
});
vartableTdWidths=newArray();
vartableWidth=0;
vartableTr0Width=0;
vartableThNum=0;
vartableTr1Width=0;
tableWidth=$('.table-scrolltable').css('width').replace('px','');
tableThNum=$('.table-scrolltr:eq(0)').children('th').length;if($('.table-scrolltr').length==1){//headeronlyif(tableWidth>tableTr0Width){
$('.table-scrolltr:eq(0)').children('th').each(function(i){
$(this).width(parseInt(($(this).css('width').replace('px',''))
+parseInt(Math.floor((tableWidth-tableTr0Width)/tableThNum)))+'px');
});
}
}else{//headerandbody
tableTr1Width=$('.table-scrolltr:eq(1)').css('width').replace('px','');
$('.table-scrolltr:eq(1)').children('td').each(function(i){
tableTdWidths[i]=$(this).css('width').replace('px','');
});
$('.table-scrolltr:eq(0)').children('th').each(function(i){if(parseInt($(this).css('width').replace('px',''))>
parseInt(tableTdWidths[i])){
tableTdWidths[i]=$(this).css('width').replace('px','');
}
});if(tableWidth>tableTr1Width){
//setallthtdwidth
$('.table-scrolltr').each(function(i){
$(this).children().each(function(j){
$(this).css('min-width',(parseInt(tableTdWidths[j])
+parseInt(Math.floor((tableWidth-tableTr1Width)/
tableThNum)))+'px');
});
});
}else{
//method1:setallthtdwidth
$('.table-scrolltr').each(function(i){
$(this).children().each(function(j){
$(this).css('min-width',tableTdWidths[j]+'px');
});
});
}
}
});

网上也有很多的例子，但是实现的效果不是想要的，自己工作需要做了一下，画面不好看，重点看效果，如有问题请指正！
