lua对表按类组装排序

方案一：
拆分表再组装表

local TaskType={
    zhixian="zhixian",
    zhuxian="zhuxian",
    shijie="shijie"
}

local Task=
{
    [1]={type=TaskType.zhuxian,name="主线1"},
    [2]={type=TaskType.shijie,name="世界1"},
    [3]={type=TaskType.zhixian,name="支线1"},
    [4]={type=TaskType.zhixian,name="支线2"},
    [5]={type=TaskType.shijie,name="世界2"},
    [6]={type=TaskType.zhuxian,name="主线2"},
}

local taskspr={}
local shijie={}
local zhuxian={}
local zhixian={}

function chaifen()
for  curIndex = 1, #Task do
		
    if Task[curIndex].type == TaskType.shijie then
			--print(Task[curIndex].name)
		table.insert(shijie,Task[curIndex])
    end
    if Task[curIndex].type == TaskType.zhuxian then
		table.insert(zhuxian,Task[curIndex])
    end
    if Task[curIndex].type == TaskType.zhixian then
		table.insert(zhixian,Task[curIndex])
    end
	
end
end
--表的拼接，在原表的基础上附加另一table
function append(tableA, tableB)
    for i = 1, #tableB, 1 do
        tableA[#tableA+1] = tableB[i]
    end
    return tableA
end

function  taskSort( taskspr )
   for _,quest in pairs(taskspr) do
        print(quest.name)
   end
end
 chaifen(Task)
taskspr=append(taskspr,shijie)
taskspr=append(taskspr,zhuxian)
taskspr=append(taskspr,zhixian)


taskSort(taskspr)

方案二：
对表内元素进行交换位置

local TaskType={
    zhixian="zhixian",
    zhuxian="zhuxian",
    shijie="shijie"
}

local Tasktab=
{
    [1]={type=TaskType.zhuxian,name="主线3"},
    [2]={type=TaskType.shijie,name="世界1"},
    [3]={type=TaskType.zhixian,name="支线1"},
    [4]={type=TaskType.zhixian,name="支线2"},
    [5]={type=TaskType.shijie,name="世界2"},
    [6]={type=TaskType.zhuxian,name="主线2"},
}

function jiaohuan(index1,index2)
	local temp=Tasktab[index1]
	Tasktab[index1]=Tasktab[index2]
	Tasktab[index2]=temp
end

function chaifen2(Task)
	local index=1
	local zhuxianindex=index
	local zhixianindex=index
	for  curIndex = 2, #Task do
		if Task[curIndex].type == TaskType.shijie then
			jiaohuan(index,curIndex)
			index=index+1
			zhuxianindex=index+1
		end
		
		if Task[curIndex].type == TaskType.zhuxian then
			jiaohuan(zhuxianindex,curIndex)
			zhuxianindex=zhuxianindex+1
				zhixianindex=zhuxianindex+1
		end
	--[[]]--
		if Task[curIndex].type == TaskType.zhixian then
				jiaohuan(zhixianindex,curIndex)
				zhixianindex=zhixianindex+1
		end
	end
end

function  taskprint( taskspr )
   for _,quest in pairs(taskspr) do
        print(quest.name)
   end
end

chaifen2(Tasktab)
taskprint(Tasktab)
