table.putvarcol - Function

3.2.1 put a specific column (for variable arrays)

Description

putcol can only used if values in the column cells to put have the same shape. putvarcol addresses this limitation by passing the values as a record instead of an array. Each field in the record contains the value for a column cell. So the length of the record has to match the number of rows to put. If a value is the unset value, no put is done for that row.

Arguments


Inputs
columnname	Name of column
	allowed:	string
	Default:
value	Record with values
	allowed:	record
	Default:
startrow	First row to put (default 0)
	allowed:	int
	Default:	0
nrow	Number of rows to put (default -1 means till the end)
	allowed:	int
	Default:	-1
rowincr	Increment in rows to put (default 1)
	allowed:	int
	Default:	1

Returns
bool

Example

  tb.open("3C273XC1.MS",nomodify=False)
  gain=tb.getvarcol("DATA", 0, 10)
  tb.putvarcol("Gain", gain, 10, 10)
  tb.flush()

This example copies the values from row 0-9 to row 10-19.
