Delphi中使用XlsReadWriteII
在Delphi中读取Excel文件，使用CreateOleObject的方式挺讨厌的，一直搞不定，输出了文件之后，总会在系统中打开一个Excel，就算Quit也不行，一个程序中使用的多了，还不定搞出什么事情来。狠狠心找个其它的东西来代替，于是发现了XlsReadWriteII。
使用之后发现这个东西真不错，简单好用。不管是读还是写均轻松搞定。下面是Demo中的代码。
写文件代码，包括对格式的定制：
XLS.Filename := ‘FormatSample.xls’;
XLS.Clear;
// Add format #0//先添加格式即ForMat:控件有一个默认的格式，序号为0，以后每添加一个，序号就加1
with XLS.Formats.Add do begin
FontIndex := XLS.Fonts.AddIndex;
XLS.Fonts[FontIndex].Name := ‘Courier new’;
XLS.Fonts[FontIndex].Size := 14;
XLS.Fonts[FontIndex].Color := xcRed;
end;
// Add format #1
with XLS.Formats.Add do begin
FontIndex := XLS.Fonts.AddIndex;
XLS.Fonts[FontIndex].AssignTFont(Font);
end;
// Add format #2
with XLS.Formats.Add do begin
FillPatternForeColor := xcLilac;
end;
// Add format #3
with XLS.Formats.Add do begin
BorderTopColor := xcBlue;
BorderBottomColor := xcBlue;
BorderTopStyle := cbsThin;
BorderBottomStyle := cbsThick;
end;
// Add format #4
// ShortDateFormat is a Delphi global variable for the local date format.
with XLS.Formats.Add do begin
NumberFormat := ShortDateFormat;
end;
XLS.Sheets[0].WriteString(1,2,0,’Format #0′);
XLS.Sheets[0].WriteString(1,3,1,’Format #1′);
XLS.Sheets[0].WriteString(1,4,2,’Format #2′);
XLS.Sheets[0].WriteString(1,5,3,’Format #3′);
XLS.Sheets[0].WriteNumber(1,6,4,Date);
XLS.Write; //如果需要另存为一个文件，改FileName之后再写一次，如需更改工作簿的名称，设置Sheets[0].Name就可以了。
读取文件代码：
var
Col,Row: integer;
Sum: double;
begin
if edFilename.Text = ” then begin
ShowMessage(‘Filename is missing’);
Exit;
end;
Sum := 0;
XLS.Filename := edFilename.Text;
XLS.Read; //此行不能省，否则读取不到数据
XLS.Sheets[0].LastCol := 255;
XLS.Sheets[0].LastRow := 65535;
for Col := XLS.Sheets[0].FirstCol to XLS.Sheets[0].LastCol do begin
for Row := XLS.Sheets[0].FirstRow to XLS.Sheets[0].LastRow do begin
if (Row < Grid.RowCount) and (Col < Grid.ColCount) then
Grid.Cells[Col + 1,Row + 1] := XLS.Sheets[0].AsFmtString[Col,Row];
if XLS.Sheets[0].CellType[Col,Row] = ctFloat then
Sum := Sum + XLS.Sheets[0].AsFloat[Col,Row];
end;
end;
lblSum.Caption := Format(‘The sum of all numeric cells are: %.2f’,[Sum]);
Grid.Invalidate;
end;

XLsReadWrite 制作Excel时控制列的的格式
分类： delphi2011-08-06 14:35116人阅读评论(0)收藏举报
最近研究下XlsReadWrite控件的使用。
其中，学会了在制作Excel时如何控制一整列的格式，如文本格式
先添加格式即ForMat:控件有一个默认的格式，序号为0，以后每添加一个，序号就加1
with XLS.Formats.Add do begin
FormatOptions := [foWrapText];
HorizAlignment := chaCenter;//对齐方式
NumberFormat := ‘@’;//主要设置该属性的值
VertAlignment := cvaCenter;
end;
然后添加当前Sheet中列的格式，语句如下：
with XLS.Sheets[0].ColumnFormats.Add do
begin
Col1:=2;//起始列的位置
Col2:=3;//结束列的位置
FormatIndex:=4;//ForMat对应的序号
end;
///////////////////////////////////////////////////////////////

用XlsReadWrite控件的时候怎样合并单元格？
我查到了，XLSReadWriteII.Sheets[0].MergedCells.Add(Col1,Row1,Col2,Row2);

Delphi编程保存数据到Excel文件(3)：使用XLSReadWriteII控件
今天采用XLSReadWriteII控件来完成10×10的乘法表，发现它很灵活，实现的功能比较多，基本能满足所以的需求。
代码片断如下：

procedure TForm1.Button1Click(Sender: TObject);
Var
i,j:Integer;
begin
XLS.Sheets[0].Name:= ‘Ten times table(乘法表)’; //给工作表命名
//General settings 常规的格式设置
With XLS.Sheet[0].Range.ItemsRef[‘B2:M14’] do begin
FontSize := 12;
FontStyle:= [xfsBold];
FillPatternForeColor := TExcelColor(45);
HorizAlignment:=chaCenter;
end;
//Title 标题
With XLS.Sheet[0].Range.ItemsRef[‘B2:M2’] do begin
Merged:=true;
HorizAlignment:=chaCenter;
FontSize := 14;
end;
XLS.Sheet[0].AsStringRef[‘B2’] := ‘Ten Times Table(乘法表)’;
//columns header 列头
With XLS.Sheet[0].Range.ItemsRef[‘C3:M3’] do begin
FillPatternForeColor := TExcelColor(53); //Interior.ColorIndex := 53;
FontColor := xcWhite;
end;
//rows header 行头
With XLS.Sheet[0].Range.ItemsRef[‘B4:B14’] do begin
FillPatternForeColor := TExcelColor(53);
FontColor := xcWhite;
end;
//Table values 表内值
for j := 0 to 10 do begin //循环各列
//column header 列头 (先列后行 基于0开始)
XLS.Sheets[0].AsInteger[2+j, 2] := j;
//row header 行头 (先列后行 基于0开始)
XLS.Sheets[0].AsInteger[1,3+j]:= j;
//time table 表内值
for i := 0 to 10 do begin //循环各行
XLS.Sheets[0].AsInteger[2+j,3+i]:= i * j;
end;
end;
XLS.Filename := ‘TenTimesTable.xls’; //保存到文件
XLS.Write;
MessageDlg(‘TenTimesTable.xls is created’, mtInformation, [mbOk], 0);
end;

使用NativeExcel2控件
这个控件非常好，非常的简捷，尤其是Range对象操作使用起来非常方便，值得推荐。
代码片断如下：
procedure TForm1.Button1Click(Sender: TObject);
Var Book: IXLSWorkbook; //申明工作薄
ws: IXLSWorksheet; //申明工作表
i, j: integer;
begin
//Create workbook 创建工作薄
Book := TXLSWorkbook.Create;
//Add new sheet 在工作薄中加一个新的工作表
ws := Book.Sheets.Add;
ws.Name := ‘Ten times table(乘法表)’; //给工作表命名
//General settings 常规的格式设置
With ws.Range[‘B2’, ‘M14’] do begin
Font.Size := 12;
Font.Bold := true;
ColumnWidth := 5.71;
Interior.ColorIndex := 45;
Borders.ColorIndex := xlColorIndexAutomatic;
HorizontalAlignment := xlHAlignCenter;
end;
//Title 标题
With ws.Range[‘B2’, ‘M2’] do begin
Merge(false);
Font.Size := 14;
Value := ‘Ten Times Table(乘法表)’;
end;
//columns header 列头
With ws.Range[‘C3’, ‘M3’] do begin
Interior.ColorIndex := 53;
Font.Color := clWhite;
end;
//rows header 行头
With ws.Range[‘B4’, ‘B14’] do begin
Interior.ColorIndex := 53;
Font.Color := clWhite;
end;
//Table values 表内值
for i := 0 to 10 do begin
//column header 列头
ws.Cells.Item[3, i + 3].Value := i;
//row header 行头
ws.Cells.Item[i + 4, 2].Value := i;
//time table 表内值
for j := 0 to 10 do begin //先行后列
ws.Range[‘C4’, ‘M14’].Item[i + 1, j + 1].Value := i * j;
end;
end;
Book.SaveAs(‘TenTimesTable.xls’); //保存到文件
MessageDlg(‘TenTimesTable.xls is created’, mtInformation, [mbOk], 0);
end;

下面附带了我写的一个DBGridToExcel控件，功能是把DBGrid中的数据导出到Excel中。大家可以学习一下，做为参考。为个控件中包括了使用属性，方法和我们将在下一篇中讲到的“事件”。

附1: 安装自制控件的方法：
(1).在Component菜单中，选择”Install Component…”.
(2).在Unit File name 后面单击“…”，选择”*.pas”控件的单元文件，再点击OK。在出现的窗口中单击”install”，即安装完毕。
新装的控件即出现在你的面板中。

附2: TDBGridToExcel控件的全部源码，把它拷贝到记事本中，存为.pas文件即可。
unit DBGridToExcel;

{ 安装： }
{ 把附件保存，然后用Delphi打开这个GridToExcel.Pas文件， }
{ 选择Delphi菜单–〉Component–>Install Component， }
{ 然后选择Install即可。安装之后，在控件面板的Samples页面上面， }
{ 熟悉之后，你可以试着设置一些复杂的属性，其他的自己摸索吧， *}
