RichEdit Table

[tomkupitz]

Hallo,

ich habe hier ein Stück Quelltext gefunden. Damit möchte ich eine Tabelle in ein RichEdit einfügen. Geht auch solange rows.cCell := 1; ist. Ansonsten gibt es einen Fehler. Habt ihr einen Lösungsansatz?

Code:

unit RichEditInsertTableUnit1;

interface

uses
  Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics,
  Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.StdCtrls, Vcl.ComCtrls;

type
  TForm1 = class(TForm)
    RichEdit1: TRichEdit;
    procedure FormClick(Sender: TObject);
  private
    { Private-Deklarationen }
  public
    { Public-Deklarationen }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

type
  _tableRowParms = record
     cbRow           : BYTE;        // Count of bytes in this structure
     cbCell          : BYTE;        // Count of bytes in TABLECELLPARMS
     cCell           : BYTE;        // Count of cells

                                    // 4 bit - Keep row together (\trkeep}
                                    // 5 bit - Keep row on same page as following row (\trkeepfollow)
                                    // 6 bit - Wrap text to right/left (depending on bAlignment) (see \tdfrmtxtLeftN, \tdfrmtxtRightN)
                                    // 7 bit - lparam points at single struct valid for all cells
     cpStartRow      : LONGINT;     // The character position that indicates where to insert table. A value of –1 indicates the character position of the selection.
     bTableLevel     : BYTE;        // The table nesting level (EM_GETTABLEPARMS only).
     iCell           : BYTE;        // The index of the cell to insert or delete (EM_SETTABLEPARMS only).
  end;
