    Maybe here would be easier to not	include this column in T_COLS, 
  but in upper layer functions it is easier	just to know the nuber of column 
  that we don't want to filter, because there usualy already 
  exists T_COLS array with all columns. 
    When all coulmns should be filtered it is neccesary to input 
  number higher than number of T_COLS array size.
