EXCEL operation commands in Delphi

It is best to use Comobj to use Excel, which can achieve full control of excel.

However, this method does not provide code prompts in Delphi, but there are some ways to use the Server control!
Below is the use of comobj, the use of Server is not put! In addition, you need to release Variant once it is used up.
This is better (ExcelApp: = Unassigned ;)

Use Comobj
(1) Use the dynamic creation method
First, create an Excel Object and use ComObj:
Var ExcelApp: Variant;
ExcelApp: = CreateOleObject ('excel. application ');
1) display the current window:
ExcelApp. Visible: = True;
2) Change the Excel title bar:
ExcelApp. Caption: = 'app calls Microsoft Excel ';
3) Add a new workbook:
ExcelApp. WorkBooks. Add;
4) open an existing workbook:
ExcelApp. WorkBooks. Open ('C:/Excel/Demo.xls ');
5) set 2nd worksheets as active worksheets:
ExcelApp. WorkSheets [2]. Activate;
Or
ExcelApp. WorksSheets ['sheet2']. Activate;
6) assign values to cells:
ExcelApp. Cells []. Value: = 'column 4 in the first row ';
7) set the width of the specified column (unit: number of characters). Take the first column as an example:
ExcelApp. ActiveSheet. Columns [1]. ColumnWidth: = 5;
8) set the height of the specified row (unit: lbs) (1 lbs = 0.035 cm). Take the second behavior as an example:
ExcelApp. ActiveSheet. Rows [2]. RowHeight: = 1/0. 035; // 1 cm
9) insert a paging character before Row 3:
ExcelApp. WorkSheets [1]. Rows [8]. PageBreak: = 1;
10) Delete the paging character before the 8th column:
ExcelApp. ActiveSheet. Columns [4]. PageBreak: = 0;
11) Specify the border line width:
ExcelApp. ActiveSheet. Range ['b3: D4 ']. Borders [2]. Weight: = 3;
1-left 2-Right 3-Top 4-bottom 5-oblique (/) 6-oblique (/)
12) Clear the cell formula in the fourth column of the first row:
ExcelApp. ActiveSheet. Cells [1, 4]. ClearContents;
13) set the font attribute of the first line:
ExcelApp. ActiveSheet. Rows [1]. Font. Name: = 'shanghai ';
ExcelApp. ActiveSheet. Rows [1]. Font. Color: = clBlue;
ExcelApp. ActiveSheet. Rows [1]. Font. Bold: = True;
Excelapp. activesheet. Rows [1]. Font. Underline: = true;
14) set the page:
A. header:
Excelapp. activesheet. pagesetup. centerheader: = 'report demo ';
B. footer:
Excelapp. activesheet. pagesetup. centerfooter: = 'page & P ';
C. The header to the top margin is 2 cm:
Excelapp. activesheet. pagesetup. headermargin: = 2/0. 035;
D. footer end margin 3 cm:
Excelapp. activesheet. pagesetup. headermargin: = 3/0. 035;
E. Top margin 2 cm:
Excelapp. activesheet. pagesetup. topmargin: = 2/0. 035;
F. The bottom margin is 2 cm:
Excelapp. activesheet. pagesetup. bottommargin: = 2/0. 035;
G. The left side is 2 cm:
Excelapp. activesheet. pagesetup. leftmargin: = 2/0. 035;
H. Right side: 2 cm:
Excelapp. activesheet. pagesetup. rightmargin: = 2/0. 035;
I. horizontal center of pages:
Excelapp. activesheet. pagesetup. centerhorizontally: = 2/0. 035;
J. Center the page vertically:
ExcelApp. ActiveSheet. PageSetup. CenterVertically: = 2/0. 035;
K. Print the cell network cable:

B. ExcelApp. ActiveSheet. Columns [1]. Delete;
18) print the preview Worksheet:
ExcelApp. ActiveSheet. PrintPreview;
