When the scrollbar is displayed, the table header is not aligned with the content, and the JS script controls

/* Set height, scroll bar */
Other Div Heights
var tbheight = document.getElementById ("Div_top"). ScrollHeight + document.getElementById ("Div_tools_bar"). Scrollheight+document.getelementbyid ("Div_tools_bar2"). Scrollheight+document.getelementbyid ("Tbtop"). ScrollHeight;
ScrollBar Div Height-other Div heights, out of display scroll bars
var DIVTB = document.documentelement.clientheight-tbheight-30;
No alignment solution, screen minus scrollbar width
var winwidth = document.documentelement.clientwidth-16;

var tbheight2 = "Height:" +string (DIVTB) + "Px;overflow:auto; Overflow-x:hidden; ";
var tbwidth2 = "width:" +string (winwidth) + "PX;";

scroll bar Div
$ ("#divtblist"). attr ("style", tbheight2);
Table Head TB
$ ("#tbtop"). attr ("style", tbwidth2);
$(". Gridbar "). attr (" style ", tbwidth2);
