How would you get this to remove a string value from a table?

print(script.Name..' loaded')
local players= game.Players

local surviving= { }

roundActive= false
intermission= true

game.Players.PlayerAdded:connect(function(player)
    table.insert(surviving, player.Name)
        print(player.Name..' has joined the game')
        print(table.concat(surviving, ', '))
    player.CharacterAdded:connect(function(character)
        character.Humanoid.Died:connect(function()
            table.remove(surviving, player.Name)
            print(player.Name..' has died')
        end)
    end)
end)

game.Players.PlayerRemoving:connect(function(player)
if surviving:findFirstChild(player.Name) then
    table.remove(surviving, player.Name)
else end
    print(player.Name..' has left')
end)

function getNewList()
local plr= players:GetChildren()
    for i= 1,#plr do
        if surviving:findFirstChild(plr[i].Name) then
            print(plr[i].Name..' is already in the roster')
        else
            table.insert(surviving, plr[i].Name)
                print(plr[i].Name..' added to the roster')
        end
    end
end

function announceSurvivors()
    print(table.concat(surviving, ', '))
end

The FindFirstChild method does not work with arrays(tables).

for key,value in pairs(surviving) do -- the pairs function is not necessary. 
    if player.Name==value then
        --  code
    end
end

The table.remove function removes the value at the index given. To remove a specific value you can loop through the table.

function removeValue(tab, val)
    for o, n in pairs(tab) do
        if val == n then
            table.remove(tab, o)
        end
    end
end

removeValue(surviving, player.Name)
