方法一，根据更新的次数，每更新30次数据，刷新一次，以降低刷新频率，减少系统消耗

import win.ui;
import godking.vlistEx
/*DSG{{*/
var winform = win.form(text="aardio form";right=749;bottom=699)
winform.add(
vlistEx={cls="vlistEx";text="自定义控件";left=10;top=10;right=750;bottom=610;z=1}
)
/*}}*/

winform.show();
winform.vlistEx.setColumns({"编号","语文","数学"},{250,250,-1}/*列宽*/,/*格式*/)
var list = {}
winform.vlistEx.setCustomAdapter(10000,function(row,col){
        return list[[row]][[col]]; 
})
var index=1;
winform.vlistEx.autoRedraw = false;
winform.setInterval( 
    function(){
        list[index] = { index,..math.random(50,100),..math.random(50,100)};
        if index<10000 index = index +1;    
        else index = 1;
        if !(index%30) {
            winform.vlistEx.redraw(true);
            winform.vlistEx.ensureVisible(index);
        }
    },0
)
win.loopMessage();

方法二，更新数据与刷新表格，分别用2个时钟控制，互不干扰。

import win.ui;
import godking.vlistEx
/*DSG{{*/
var winform = win.form(text="aardio form";right=749;bottom=699)
winform.add(
vlistEx={cls="vlistEx";text="自定义控件";left=10;top=10;right=750;bottom=610;z=1}
)
/*}}*/

winform.show();
winform.vlistEx.setColumns({"编号","语文","数学"},{250,250,-1}/*列宽*/,/*格式*/)
var list = {}
winform.vlistEx.setCustomAdapter(10000,function(row,col){
        return list[[row]][[col]]; 
})
var index=1;
winform.vlistEx.autoRedraw = false;
winform.setInterval( 
    function(){
        list[index] = { index,..math.random(50,100),..math.random(50,100)};
        if index<10000 index = index +1;    
        else index = 1;
    },0
)
winform.setInterval( 
    function(){
        winform.vlistEx.redraw(true);
        winform.vlistEx.ensureVisible(index);
    },500
)
win.loopMessage();

效果
