后来使用这样的方法来改变标头的宽度。
function set_width(table1,table2)
{var allstr=0; for(var i=0; i<table1.rows[0].cells.length; i++)
{
allstr=allstr+table1.rows[0].cells[i].innerText
}for(var i=0; i<table1.rows[0].cells.length; i++)
{
table2.rows[0].cells[i].width=(100*table1.rows[0].cells[i].innerText.length/allstr.length)+"%"
}}
可是这样没办法得到哪列最宽,而且有的单元格内还有多行数据,但宽度不一定最长,这样就更出现误差了。
