			Also note that foreachi starts at index [1], increments the index by one repeatedly, and stops running as soon as it reaches a nil value. This is an example:

			> t = { [0] = "zero", --will not be counted
			[1] = "one", --will be counted; 1
			[2] = "two", --will be counted; 2
			[3] = "three", --will be counted; 3
			["four"] = "four", --will not be counted; returns 3
			[5] = "five" } --will never be reached
			> foreachi(t, print)
			1 one
			2 two
			3 three

table.foreachi(table, f)

Apply the function f to the elements of the table passed. On each iteration the function f is passed the index-value pair of that element in the table. This is similar to table.foreach() except that index-value pairs are passed, not key-value pairs. If the function f returns a non-nil value the iteration loop terminates.

> t = { 1,2,"three"; pi=3.14159, banana="yellow" }
> table.foreachi(t, print)
1 1
2 2
3 three

Note in the example only the indexed elements of the table are displayed. See the TablesTutorial for more information on key-value and index-value pairs.
