  I read many times the manual and nothing there answer my questions.
  
  1) There is no answer to define the row header width (i try several alternatives, but no one work properly), the OnCalcWidth apply only to columns not to row header (first column of the dbcrosstab object, e.g. Employee Name).
  
  2) In the manual is described a way to format the Grand Total values, but if I format in then cross tab editor, on the report preview an error occur, fastreport try to format the title "Total" with the numeric mask, intead of format the values.
  This error occur when I execute do program on the Delphi IDE.
  
  The fast-report version is 3.06 trial and I??m using the DbCrossTab object.
  
  Thanks!

  i have the same problem with the first column width (row header), i cannot set the width.
  
  i have dbcrosstab report with 5 columns (1 row header + 4 cols) plus grand total, the first column (text) can have 250 chars, but i want to set the width to 450 pixels.
  
  OnCalcWidth i can set all the columns width, except the first column (row header), how can i do this??
  
  thx,

  Change the frxCrossMatrix.pas file:

  procedure TfrxCrossMatrix.CalcBounds;
  ...
  begin
    ColumnItems := FColumnHeader.TerminalItems;
    RowItems := FRowHeader.TerminalItems;
  
    { calculate the widths of columns and the heights of rows }
    FColumnHeader.CalcSizes(FMaxWidth, FMinWidth);
    FRowHeader.CalcSizes(FMaxWidth, FMinWidth);
  ...
  

  
  Now you can set the MaxWidth/MinWidth properties to limit the width of the row header.

  I can't do this because I'm using the FR3 trial, but I'm happy because now I know that this is possible.
  
  Thanks!
