How to create a row or table with incrementing numbers?

A - answer To generate a sequence of numbers (with a specified starting number and an increment) you can use the TCOUNT Express Tool, manually entered table expressions or - for an automated function - you can use the free NumTab tool by CAD Studio (see

NumTab creates and populates a calculated table (introduced in AutoCAD 2006) with fields (cells) specifying the incrementing numbers. You can define any expression as the increment (+1, *2, -3; arithmetic and geometric sequences). If you later change the starting number (or a number in a middle of the sequence), the rest of the sequence is automatically recalculated. You can edit the number array together, as table.

You can create tables of type:

2000 2001 2002 2003 2004 2005 2006 2007


 2  4  8  16
32 64 128 256
When you change "5" to "8" in:
1 2 3  4  5  6
7 8 9 10 11 12
the table updates automatically to:
1  2  3  4  8  9
10 11 12 13 14 15
