code: def putcell(self, columnname, rownr, value):
          
          self._putcell(columnname, rownr, value)
docs: Put a value into one or more table cells.
  
          The columnname and (0-relative) rownrs indicate the  table cells.
          rownr can be a single row number or a sequence of row numbers.
          If multiple rownrs are given, the given value is put in all those rows.
  
          The given value has to be convertible to the data type of the column.
          If the column contains scalar values, the given value must be a scalar.
          The value for a column holding arrays can be given as:
  
          - a scalar resulting in a 1-dim array of 1 element
          - a sequence (list, tuple) resulting in a 1-dim array
          - a numpy array of any dimensionality
  
          Note that the arrays in a column may have a fixed dimensionality or
          shape. In that case the dimensionality or shape of the array to put
          has to conform.
