From TableLibraryTutorial of lua-users.org. table.foreachi(table, f) foreaci(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
