+Currently only used by \helpref{wxDb::GetCatalog}{wxdbgetcatalog} internally
+and \helpref{wxDbInf}{wxdbinf} class, but may be used in future releases for
+user functions. Contains information describing the table (Name, type, etc).
+A pointer to a wxDbColInf array instance is included so a program can create a
+\helpref{wxDbColInf}{wxdbcolinf} array instance (using
+\helpref{wxDb::GetColumns}{wxdbgetcolumns})
+to maintain all information about the columns of a table in one memory
+structure.
+
+Eventually, accessor functions will be added for this class
+

+
+\section{\class{wxDbGridColInfo}}\label{wxdbgridcolinfo}
+
+This class is used to define columns to be shown, names of the columns,

+a Table or query in a \helpref{wxGrid}{wxgrid}

+
+It is important to note that this class is merely a specifier to the \helpref{wxDbGridTableBase}{wxdbgridtablebase}

+not have any effect.

+\docparam{title}{The column label to be used in the grid display}
+
+\wxheading{Remarks}
+
+As wxDbTable must be defined with to have columns which match those to by a wxDbGridColInfo
+info structure as this is the structure which informs the grid of how you want to display your
+\helpref{wxDbTable}{wxdbtable}. If no datatype conversion or the referenced column number does not exist the
+the behavior is undefined.
+
+See the example at \helpref{wxDbGridColInfo::wxDbGridColInfo}{wxdbgridcolinfo}.
+
+\section{\class{wxDbGridTableBase}}\label{wxdbgridtablebase}
+
+You can view a database table in a grid using this class.
+
+If you are deriving your own wxDbTable subclass for your table , then you may consider
+overriding GetCol() and SetCol() to provide calculated fields. This does work but care should
+be taken when using wxDbGridTableBase in this way.
+
+The constructor and AssignDbTable() call allows you to specify the ownership if the wxDbTable
+object pointer. If you tell wxGridTableBase to take ownership , it will delete the passed wxDbTable
+when an new on is assigned or wxGridTableBase's destructor is called.
+However no checks for aliasing are done so Assign(table,..,true); Assign(table,..,true);
+is an error. If you need to requery an table object the preferred way is
+that the client keeps ownership.

+\begin{verbatim}
+ // First step, let's define wxDbTable

+ table->SetColDef (1, "column 1", DB_DATA_TYPE_VARCHAR, &string_name,
+ SQL_C_LONG, sizeof(string_name), false);

+
+\func{}{wxDbGridTableBase}{\param{wxDbTable *}{tab}, \param{wxDbGridColInfo *}{ColInfo},

+
+Constructor.
+
+\wxheading{Parameters}
+
+\docparam{tab}{ The database table you want to display. Must be opened and queried before display the grid.
+See the example \helpref{above}{wxdbgridtablebase}.}
+\docparam{ColInfo}{ Columns titles, and other values. See \helpref{wxDbGridColInfo}{wxdbgridcolinfo}.}
+\docparam{count}{You can use a query result set (wxUSE\_QUERY, to use wxDbTable::Count(wxDbTable::Count()
+ or you can fix the total number of rows (count >= 0) to display, or specify it if you already know the size in avoid calling }
+
+\docparam{takeOwnership}{ If true, this class deletes wxDbTable when it stops

+
+\membersection{wxDbGridTableBase::ValidateRow}\label{wxdbgridtablebasevalidate}
+
+\func{void}{ValidateRow}{\param{int }{row}}
+
+It ensures that the row data is fetched from the database, and it the wxDbTable local buffer,
+the row number passed should be the grid row.
+
+\wxheading{Parameters}
+
+\docparam{row}{ Row where validation must be done. }
+
+\membersection{wxDbGridTableBase::UpdateRow}\label{wxdbgridtablebaseupdaterow}
+
+\func{bool}{UpdateRow}{\param{int }{row}}
+
+If row has changed it forces that row to be written back to the database, however support
+for detecting whether insert/update is required is currently not in wxDbTable, so this
+function is currently unsupported.
+
+\wxheading{Parameters}
+
+\docparam{row}{ Row you want to update. }

+
+\func{bool}{AssignDbTable}{\param{wxDbTable *}{tab},\param{int }{count = wxUSE\_QUERY},
+\param{bool }{takeOwnership = true}}
+
+Resets the grid for using with a new database table, but using the same columns definition.
+This can be useful when re-querying the database and want to see the changes.
+
+\wxheading{Parameters}
+
+\docparam{tab}{ Database table you want to assign to the grid. }
+\docparam{count}{ Number of rows you want to show or wxUSE\_QUERY for using a query. }
+\docparam{takeOwnership}{ If false, user must take care of deleting tab after deleting
+the wxDbGridTableBase. If true, deletion is made by destructor class. }
