How to check if a string is in a table?

In my admin script, I need to find out if the player who is chatting is listed in the table or not. Is there some type of string function that can be used to search a table?

local Admins = {"RedCombee"}

local function CheckIfAdmin(Player)
	for _,adminName in pairs(Admins) do
		--What this does is makes it so "adminName" is the words in the table Admins
		if Player.Name == adminName then  --If the player's name is the same as adminName, then:
			return true
		else --Anything else except if the player's name is the same as adminName
			return false
		end
	end
end

for _,player in pairs(game.Players:GetPlayers()) do
	--What this does it makes it so "player" is every player in the game
	player.Chatted:connect(function(message)
		if CheckIfAdmin(player) == true then --calls the function we made earlier
			--CODE HERE :)
		end
	end)
end

*Heres a TIP not a "answer" but this will get your started on the correct path ;D*

Table={'RedCombee','MessorAdmin','idjwijwdiwjdiwidjwidwidj'};

function G(Plr)
for _,v in pairs(Table) do
print(v)
if v==Plr:lower() or v==Plr.Name:lower() then
print(Plr)
end

G(game.Players.RedCombee)
