将一张表分成多个数组，每 X 个元素

Question

假设我有一个表，我想将它细分为每个 X 元素

fruits = {"banana","orange","apple","avocado","cherry","coconut"}

 -- Split every 2 elements independent of array size

fruits = {{"banana","orange"},{"apple","avodado"},{"cherry","coconut"}}

Answer 1

使用两个 for 循环，步长为 x

local function splitx(tbl, x)
  assert(x > 0)
  assert(type(tbl) == "table")
  local result = {}
  for i=1,#tbl,x do
    local item = {}
    for j=i,i+x-1 do
      if tbl[j] then
        table.insert(item, tbl[j])
      end
    end
    table.insert(result, item)
  end
  return result
end
