LabWindows中Table控件的下拉列的设置

1  先看样式

2  样式设置，双击table，添加列以后，编辑列，选择 Combo box

3  全选一列，无法添加值，只有选中一个单元格才可以添加值

-------->>>------->>

4   行的隐藏，其实不是真的隐藏行，而是把对应行的字体颜色改为白色

//历史数据显示到表格
void displayDataTableDB()
{
	char tt[80];
	//把数据显示到表格
	SetCtrlAttribute(panelHandleDb,PANELdb_WxpDataTableDB,ATTR_DIMMED,1);

	for(int i=1; i<channelCount; i++)
	{
		SetTableRowAttribute(panelHandleDb,PANELdb_WxpDataTableDB,i,ATTR_ROW_HEIGHT,30);

		SetTableCellVal(panelHandleDb,PANELdb_WxpDataTableDB,MakePoint(1,i),WxpAqurieData[i].w1NodeName);
		sprintf(tt,"%.2f",WxpAqurieData[i].w1WinSpeed);
		SetTableCellVal(panelHandleDb,PANELdb_WxpDataTableDB,MakePoint(2,i),tt);
		sprintf(tt,"%.2f",WxpAqurieData[i].w1EnvTemp);
		SetTableCellVal(panelHandleDb,PANELdb_WxpDataTableDB,MakePoint(3,i),tt);


		SetTableCellVal(panelHandleDb,PANELdb_WxpDataTableDB,MakePoint(5,i),WxpAqurieData[i].w2NodeName);
		sprintf(tt,"%.2f",WxpAqurieData[i].w2WinSpeed);
		SetTableCellVal(panelHandleDb,PANELdb_WxpDataTableDB,MakePoint(6,i),tt);
		sprintf(tt,"%.2f",WxpAqurieData[i].w2EnvTemp);
		SetTableCellVal(panelHandleDb,PANELdb_WxpDataTableDB,MakePoint(7,i),tt);

		//全部调整为黑色
		for(int k=1; k<8; k++)
			SetTableCellAttribute (panelHandleDb,PANELdb_WxpDataTableDB, MakePoint (k, i),ATTR_TEXT_COLOR, VAL_BLACK);
		//调节隔行颜色
		if(i%2==0)
			for(int k=1; k<8; k++)
				SetTableCellAttribute (panelHandleDb,PANELdb_WxpDataTableDB, MakePoint (k, i),ATTR_TEXT_COLOR, VAL_RED);

		//判定是否隐藏
		GetTableCellVal(panelHandleDb,PANELdb_WxpDataTableDB,MakePoint(9,i),tt);

		if(strcmp(tt,"隐藏")==0)
			for(int k=1; k<8; k++)
				SetTableCellAttribute (panelHandleDb,PANELdb_WxpDataTableDB, MakePoint (k, i),ATTR_TEXT_COLOR, VAL_WHITE);
	}
	SetTableSelection(panelHandleDb,PANELdb_WxpDataTableDB,MakeRect(20,1,1,7));
	SetCtrlAttribute(panelHandleDb,PANELdb_WxpDataTableDB,ATTR_DIMMED,0);
}

这里要强调一点，表格在插入数据涉及到控件刷新，速度会非常缓慢。

才插入数据前，是表格变灰dimmed=1，也就是  SetCtrlAttribute(panelHandleDb,PANELdb_WxpDataTableDB,ATTR_DIMMED,1);

插入完毕后，是表格有效 dimmed=0，也就是 SetCtrlAttribute(panelHandleDb,PANELdb_WxpDataTableDB,ATTR_DIMMED,0);

速度会非常快，界面刷新毫无压力。
