How to manipulate a "OneDDualArrayTblValue"

Hi,

Does it exist some API which let me manipulate a OneDDualArrayTblValue?

let's say I have that table:

((("width") ((0.0 0.0) ) )
 ( 0.01 ((0.01 0.02) )
   0.02 ((0.02 0.03) )
   0.04 ((0.05 0.06) )
   0.05 ((0.06 0.07) (0.07 0.07) )
   0.06 ((0.04 0.02) )
   0.07 ((0.03 0.02) (0.06 0.04) )
   0.08 ((0.02 0.02) )
  )
)

what is the best way to insert a member (0.03 ((0.02 0.04) (0.05 0.05) ) ) between the member (0.02 ((0.02 0.03) ) ) and  (0.04 ((0.05 0.06) ) ).

Do I have too break the table and read each member then append when find the right position in a for loop.

Any suggestion is welcome.

Thanks

Tony
