create dinamically celltable

[alf]

How can I create a content of table without previosly has a class with
models.

I can cretate a header of column but when I set a list like
Arrays.aslist{"",""} only fill a first column a repite the same in
other column. I would like send a matrix colum & row to fill table
correctly.

many thanks

You can't specify a matrix to fill a CellTable.  You have to declare an object that represents each row, then add columns to pull the values out of the row.

The closest thing to a matrix is to declare the CellTable as type List<String> (CellTable<List<String>>).  Then add columns that read the associated index, so column 0 reads list.get(0), column 1 reads list.get(1), etc...  Then you can pass a List<List<String>> to setRowData().

The dev guide has a fairly simple example of CellTable:

http://code.google.com/webtoolkit/doc/latest/DevGuideUiCellWidgets.html#celltable

There is also one in the checked in javadoc, which is slightly more complicated:

http://code.google.com/p/google-web-toolkit/source/browse/trunk/user/javadoc/com/google/gwt/examples/cellview/CellTableExample.java

I don't know of an example that uses a List of Lists, but its probably better to represent your row values as specific type instead of just using a List of Strings.
