Table Methods

Methods for table manipulation.

1. table.concat

   table.concat joins a Lua list of strings and numbers into a single string, with an optional separator and index range.

   table.concat(list [, sep [, i [, j]]])
2. table.insert

   Insert a value into a Lua table at a given position, shifting later elements up. Without a position, table.insert appends to the array part of the table.

   table.insert(list, [pos,] value)
3. table.maxn (deprecated)

   table.maxn returns the largest positive numeric key in a table. Deprecated in Lua 5.2, removed in 5.3; use # or a pairs() loop.

   table.maxn(table)
4. table.move

   table.move copies a contiguous range of elements from one table to another, with optional in-place mode and correct handling of overlapping ranges.

   table.move(a1, f, e, t [,a2])
5. table.pack

   table.pack captures Lua varargs into a table with an n field that preserves the true argument count even when values are nil.

   table.pack(...): table
6. table.remove()

   table.remove() removes and returns an element from a Lua sequence, with an optional index. Trailing elements shift down to close the gap.

   table.remove(list [, pos])
7. table.sort

   table.sort reorders a Lua sequence in place using the < operator by default. Pass an optional comparator to customize ordering or sort complex elements.

   table.sort(table [, comp])
