After changing the color of a column and selecting that column and inserting a 
new column always inserts a new column with default properties (combination of 
dark blue and light blue color). I think that it should always insert a column 
with the color style of the selected column. This feature is very helpful when 
the color of the whole table is chaneged and new columns have to be inserted.
Here are the steps to be followed:

1. Create a presentation.
2. Insert a table in presentation.
3. Change the color of the whole table with the same color.
4. Insert a column or columns in to table.

You will find that the inserted column will be of the default color (blue 
combination). We have to change the color of the each column inserted column 
manually. If this feature is included in OO then it will help a lot to insert a 
column very fast in a desired way (rather than changing the color style 
manually). 

The same thing is with rows. Selecting a row and inserting a row will have the 
default color of the rows instead of having the color of the selected row.
