Sequential numbering across different data tables

[#1]

Hello all, I am pretty new to JSL, so I have this small doubt where I have 3 data tables, and each holds 12 rows. So, I want to add a line of code which gives me an output like for table1-the num col will be 1-12, for table2- the num col will be 13-24 and for table-3 the num col will be 25-36. Can you help me with this. Thank you in advance.

<JSL>

l = 117;

w = 32;

h = 43;

ls = 19.6;

ws = 16.4;

hs = 14.3;

numbers = Function({ls, ws, hs, l, w, layer},
	dt = New Table("data" || Char(layer),
		Add Rows(0),
		New Column("num", Numeric, continuous),
		New Column("length", Numeric),
		New Column("width", Numeric),
		New Column("height", Numeric),

	);
	For(length = ls / 2, length <= l, length += ls,
		For(width = ws / 2, width <= w, width += ws,
			height = Round(hs * layer, 1);

			num = N Rows(dt);
			num++;
			dt << Add Rows(1);
			:num[N Rows(dt)] = num;
			:length[N Rows(dt)] = Round(length, 2);
			:width[N Rows(dt)] = Round(width, 2);
			:height[N Rows(dt)] = Round(height, 2);
		)
	);
	Return(dt);
);

table1 = numbers(ls, ws, hs, l, w, 1);
table2 = numbers(ls, ws, hs, l, w, 2);
table3 = numbers(ls, ws, hs, l, w, 3);

take a look at the Sequence function.

Help>scripting index> search for sequence

...or, better:

Start a new workflow, start the recorder

In a data table, make a new column with a formula.

in the formula editor type this - sequence()

the functions arguments will appear, enter start as 1 and end as 12

Apply the formula.

Then turn off the workflow recorder, and viola you have a script for adding a column with a formula for a sequence of numbers.
