新发一个像 Excel 那样的表格控件，刚开始做，没有学历，水平有限，
画边框部分就用了两个月，难啊！
初步在 http://kinneng.ys168.com/ 演示
 
flexcel就很好了
 
就是讨厌 ActiveX 才使用 delphi 的，flexcel 是 ActiveX 控件，用 ActiveX 那么
我干脆用 VB，其实用 VB 也不错，就是一大堆文件令人头疼！
 
用StringGrid实现的？
 
SDM SDD
 
可否提供源代码呢？
 
用 TCustomGrid + TList 实现的
 
绘图技术一流啊。。。
 
不给源码。也要对于大家的试用说点原理什么的才好。哈哈
 
你要什么原理？我没有原理
 
我这是发布控件，不是发布技术，不是教学，也不收费。
在网上，这种表格是许多人的生计，如果哪一天，我不玩了，我也考虑像 EasyGrid 的
作者那样，公开源代码，结果就是一个菜鸟从此消失，一项技术永远定格，不会再升级，
最后沉沦，开源控件是 delphi 的卖点，它令当年的 delphi 兴起，也是令今天的delphi
衰落。
 
哈哈,同意楼主观点,对于控件,只要能达到BUG少,费用低,好用就行
 
绘图技术一流，呵呵，肯定的，绘制格子的边框为例，在绘制之前，我用了 一千二百行
代码，预先将要绘制边线，全部分析准备好，然后用几十行的代码落实绘制，这样做效果
好，速度快，没理由不一流，就是代码写得辛苦，如果急功近利，不分析，直接绘制，
即使绘出的图案一样，但闪烁明显，效果同一般老菜的作品没有区别，正所谓，要么不做，
要做就做到比商品级的更好，现在绘制边框部分，已经超过了 Excel 的水平，这个各位
可以比较，我的边框绘制效果跟 Excel 差不多，只是绘线规则不同，算法不同，而我的线
型更丰富，且允许客户自定义，这样技术门槛提高了，各位做同类东西的高手又要辛苦了。
 
控件继承TCustomGrid，但 Paint 部分我自己写，下面是 Paint 的完整代码，比 TCustomGrid 的
还要简单，但效果比它好，最主要的是适用。
procedure TEXGrid.Paint;

var
CurCol, CurRow: Longint;
AWhere, Where, TempRect: TRect;
DrawState: TGridDrawState;
begin
CurRow := ARow;
Where.Top := StartY;
if CurRow = FixedRows then
CurRow := TopRow;
while (Where.Top < StopY) and (CurRow <= TopRow + VisibleRowCount + 1) and (CurRow < RowCount)do
begin
CurCol := ACol;
if CurRow = FixedRows then
CurRow := TopRow;
Where.Left := StartX;
Where.Bottom := Where.Top + RowHeights[CurRow];
if FixedCols <> LeftCol then
if CurCol = FixedCols then
CurCol := LeftCol;
while (Where.Left < StopX) and (CurCol <= LeftCol + VisibleColCount + 1) and (CurCol < ColCount)do
begin
if FixedCols <> LeftCol then
if CurCol = FixedCols then
CurCol := LeftCol;
Where.Right := Where.Left + ColWidths[CurCol];
TempRect := Where;
InflateRect(TempRect, 1, 1);
if (Where.Right > Where.Left) and RectVisible(Canvas.Handle, TempRect) then
begin
DrawState := IncludeDrawState;
AWhere := CellInfos[CurCol, CurRow].Merge;
if CellInRect(AWhere, FAnchor.X, FAnchor.Y) then
Include(DrawState, gdFocused);
if PointInGridRect(CurCol, CurRow, Sel) then
Include(DrawState, gdSelected);
if not (gdFocused in DrawState) or not (goEditing in Options) or not EditorMode or (csDesigning in
ComponentState) then
DrawCell(CurCol, CurRow, Where, DrawState);
end;
Where.Left := Where.Right + DrawInfo.Horz.EffectiveLineWidth;
Inc(CurCol);
end;
Where.Top := Where.Bottom + DrawInfo.Vert.EffectiveLineWidth;

end;
end;

DrawInfo.Vert.GridBoundary, FixedColor, [gdFixed]);
end;

if not UseRightToLeftAlignment then

有在QQ问我怎么绘制边框，这里将分析框线部分完整贴出，占程序的 1/20，它分析一个格子 4 条边的
边框如何绘制，按挨首7468标准，菜鸟作品是没有注释的。这里没有使用技巧，全部都是普通代码，组
织起来实现一个巨繁复的算法。
许多人看了或者觉得没意思，或者看晕了，但控件就是这么做出来的，x,y 是待绘格子的坐标。
