How to create tables in Word

Problem/Question/Abstract:

Is is possible to create a table in Word via OLE Automation and to specify the value of each cell?

Answer:

Yes. If Doc is a TWordDocument, for example:

{ ... }
var
  Tbl: Table;
  R: Range;
  Direction: OleVariant;
  { ... }
Direction := wdCollapseEnd;
R := Doc.Range;
R.Collapse(Direction);
Tbl := Doc.Tables.Add(R, 2, 4, EmptyParam, EmptyParam);
Tbl.Cell(1, 1).Range.Text := 'Row 1, Col 1';
Tbl.Cell(1, 2).Range.Text := 'Row 1, Col 2';

But doing things with individual table cells in Word is extremely slow. If you can, it's better to enter the data as (for example) comma-separated values and convert it into a table only as the last step. Here's an example:

{ ... }
const
  Line1 = 'January,February,March';
  Line2 = '31,28,31';
  Line3 = '31,59,90';
var
  R: Range;
  Direction, Separator, Format: OleVariant;
{ ... }
R := Word.Selection.Range;
Direction := wdCollapseEnd;
R.Collapse(Direction);
R.InsertAfter(Line1);
R.InsertParagraphAfter;
R.InsertAfter(Line2);
R.InsertParagraphAfter;
R.InsertAfter(Line3);
R.InsertParagraphAfter;
Separator := ',';
Format := wdTableFormatGrid1;
R.ConvertToTable(Separator, EmptyParam, EmptyParam, EmptyParam, Format, EmptyParam,
  EmptyParam, EmptyParam, EmptyParam, EmptyParam, EmptyParam, EmptyParam,
  EmptyParam, EmptyParam);
{ ... }
