Hi Nico,
Thank you for your answer.

But, I never use the TppMatrix. Could you help me uses it giving it a small
example of as declares it in the Source of the Delphi? What I need to
declare in USES? In which event of the Cross Tab I can use the Matrix?

I'm waiting a answer.
Thank you one more time.

Hi Diogo,

There is extensive documentation of the TppMatrix object in the
ReportBuilder help file. You can access the TppMatrix object using the
TppCrossTab.Matrix property. From there you can use the DeleteColumn,
InsertColumn, and AppendColumn methods to manipulate the crosstab as you
need.

Niko,
I?m going to make the last question about Matrix:

For example:
I don?t know the event of the Cross Tab that I could use the properties of
the Matrix. I put it on CALCDIMENSIONVALUE, ONFORMATCELL, ONGETCAPTIONTEXT,
ONGETVALUETEXT, ON PRINT and others, but when I execute de program, show the
message: "ACCESS VIOLATION ON ADRESS..."

I did not find any think about this on the help file of Report Builder.
Case that you know, I would be very been thankful.

You may need to test a few events to find one that gives you the proper
output. I would recommend starting with the DetailBand.BeforePrint.
