IDA Help: Data representation: tabular form

Syntax:
  __tabform(flags)
  __tabform(flags,lineitems)
  __tabform(flags,lineitems,alignment)
  __tabform(,lineitems,alignment)
  __tabform(,,alignment)

This keyword is used to format arrays.
The following flags are accepted:
  NODUPS do not use the `dup` keyword
  HEX    use hexadecimal numbers to show array indexes
  OCT    use octal numbers to show array indexes
  BIN    use binary numbers to show array indexes
  DEC    use decimal numbers to show array indexes

It is possible to combine NODUPS with the index radix: NODUPS|HEX

The `lineitems` and `alignment` attributes have the meaning described for
the create array command.

Example:
  Display the array in tabular form, 4 decimal numbers on a line, each number
  taking 8 positions. Display indexes as comments in hexadecimal:

  char array[16] __tabform(HEX,4,8) __dec;

  A possible array may look like:

  dd   50462976, 117835012, 185207048, 252579084; 0
  dd  319951120, 387323156, 454695192, 522067228; 4
  dd  589439264, 656811300, 724183336, 791555372; 8
  dd  858927408, 926299444, 993671480,1061043516; 0Ch

Without this annotation, the `dup` keyword is permitted, number of items on a
line and the alignment are not defined.
