[转载]: delphi中XLSReadWrite控件的使用(3)---基本应用

这是自带的一个例子，看懂这一点东西，基本的操作应该没问题了....

unit Main;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls, XLSReadWriteII4, XLSFonts4, CellFormats4, BIFFRecsII4;

type
  TfrmMain = class(TForm)
    Label1: TLabel;
    Button1: TButton;
    edFilename: TEdit;
    Button2: TButton;
    Button3: TButton;
    dlgSave: TSaveDialog;
    XLS: TXLSReadWriteII4;
    procedure Button1Click(Sender: TObject);
    procedure Button2Click(Sender: TObject);
    procedure Button3Click(Sender: TObject);
  private
    procedure AddFormats;
  public
    { Public declarations }
  end;

var
  frmMain: TfrmMain;

implementation

{$R *.dfm}

procedure TfrmMain.AddFormats;
begin
  (*Format a single cell*)
  (* 显示字符串 *)
  XLS.Sheets[].AsString[,] := 'Cell 1';
  (* 字符串颜色 *)
  XLS.Sheets[].Cell[,].FillPatternForeColor := xcYellow;
  (* 字体 *)
  XLS.Sheets[].Cell[,].FontStyle := [xfsBold,xfsItalic];

  (*Format a number cell (3 decimals and thousand separator)
  (* 格式化字符串，显示小数点后三位，千位和百位之间加个空格 *)
  XLS.Sheets[].AsFloat[,] := 12335985394.895634;
  XLS.Sheets[].Cell[,].NumberFormat := '# ##0.000';

  (* Write a string cell.  *)
  XLS.Sheet[].AsStringRef['C2'] := 'Hello';
  (* 单元格赋值 *)
  (* Set the font size of the cells in the area.
  (* 改变区域内的字体大小 *)
  XLS.Sheet[].Range.Items[,,,].FontSize := ;
  (* Set the color of the cells. *)
  (* 设置区域的颜色 *)
  XLS.Sheet[].Range.ItemsRef['B1:D4'].FillPatternForeColor := xcYellow;
  (* Set a outline border.   *)
  (* 设置外框线的外形、颜色 *)
  XLS.Sheet[].Range.ItemsRef['B1:D4'].BorderOutlineStyle := cbsThick;
  (* Set color of the outline border.  *)
  XLS.Sheet[].Range.ItemsRef['B1:D4'].BorderOutlineColor := xcRed;
  (* Make a copy of the cells.  *)
  (* 区域复制 *)
  XLS.Sheet[].Range.ItemsRef['B1:D4'].Copy(,);
  (* Move the cells. *)
  (* 区域移动 *)
  XLS.Sheet[].Range.ItemsRef['B1:D4'].Move(,);
end;

procedure TfrmMain.Button1Click(Sender: TObject);
begin
  AddFormats;
  XLS.Filename := edFilename.Text;
  (* 保存文件 *)
  XLS.Write;
end;

procedure TfrmMain.Button2Click(Sender: TObject);
begin
  dlgSave.FileName := edFilename.Text;
  if dlgSave.Execute then
    edFilename.Text := dlgSave.FileName;
end;

procedure TfrmMain.Button3Click(Sender: TObject);
begin
  Close;
end;

end.
