+

+    should implement -- and which can be implemented differently in derived
+    classes -- and a default implementation of this interface which is often
+    good enough to be used without modification, especially with not very large
+    grids for which the efficiency of attributes storage hardly matters (see
+    the discussion below).
+
+    An object of this class can be associated with a wxGrid using

+    intend to use the default provider as it is used by wxGridTableBase by
+    default anyhow.
+
+    Notice that while attributes provided by this class can be set for
+    individual cells using SetAttr() or the entire rows or columns using
+    SetRowAttr() and SetColAttr() they are always retrieved using GetAttr()
+    function.
+
+
+    The default implementation of this class stores the attributes passed to
+    its SetAttr(), SetRowAttr() and SetColAttr() in a straightforward way. A
+    derived class may use its knowledge about how the attributes are used in
+    your program to implement it much more efficiently: for example, using a
+    special background colour for all even-numbered rows can be implemented by
+    simply returning the same attribute from GetAttr() if the row number is
+    even instead of having to store N/2 row attributes where N is the total
+    number of rows in the grid.
