How do I add something to a table if it's empty?

Here I am trying to add the item name to the table. I am trying to make it short so I don't want to check if the table is empty and do an if statement which will make it twice as long. Is there another way to do this without checking if the table is empty? This also seems to do the same if theres only one item in the table.

**1.**No the event isn't the problem just in case.

**2.**I tried to do for i,v in ipairs(table) but it did the same thing or even broke the whole script.

**2.**The Item argument is a string value.

module.EquippedItems = {}


module.EquipItem = function(Item)	
	local WasEquipped = false

	for i =  1,#module.EquippedItems do
		if module.EquippedItems[i] == Item then
			WasEquipped = true
		end
	end

	if WasEquipped == true then
		
		for i = 1,#module.EquippedItems do
			if module.EquippedItems[i] == Item then
			table.remove(module.EquippedItems,i)	
			EquipItemEvent:FireServer(Item,false)
			
		if Holder_Inventory:FindFirstChild(Item) then
			local SetItem = Holder_Inventory:WaitForChild(Item)
			SetItem.BackgroundColor3 = Color3.fromRGB(163, 162, 165)
		end																					
			end
		end	
	elseif not WasEquipped then
		for i = 1,#module.EquippedItems,1 do
			if module.EquippedItems[i] == nil then
				table.insert(module.EquippedItems,i,Item)
				EquipItemEvent:FireServer(Item,true)		
		if Holder_Inventory:FindFirstChild(Item) then
			local SetItem = Holder_Inventory:WaitForChild(Item)
			SetItem.BackgroundColor3 = Color3.fromRGB(0,255,0)
		end							
			end
		end			
	end
end
