How do I create DataStores?

I understand how to retrieve things from Data Stores, thanks to the wiki, but I don't understand quite how to make one.

Say, for instance, I wanted to make a data store like this:

Store name: pointsTable "usr_"..player.PlayerId | Points

How exactly would I be able to create this? And is it possible to have multiple value columns like Points, Kills, Deaths, for example? Thank you.

Okay first off yes you can store values in columns its called a table/array and you put those in the table. here is a sample code because I'm sure you understand how to do this and I don't really understand how to explain it. if you have any more questions feel free to PM me or put a comment so I can help you out some more.

01--\\ Services //--
02local datastoreservice = game:GetService('DataStoreService')
03--\\ DataStores //--
04local datastore = datastoreservice:GetDataStore('pointsTable')
05--\\ Values //--
06local sessiondata = {}
07--\\ Functions //--
08local function onPlayerAdded(player)
09    local leaderstats = Instance.new('Folder')
10    leaderstats.Name = 'leaderstats'
11    local points = Instance.new('IntValue', leaderstats)
12    points.Name = 'Points'
13    local kills = Instance.new('IntValue', leaderstats)
14    kills.Name = 'Kills'
15    local deaths = Instance.new('IntValue', leaderstats)
16    deaths.Name = 'Deaths'
17    local key = ('user_'..tostring(player.UserId)) -- key, unique to the player
18    local data = datastore:GetAsync(key) or { -- checks if they already have data saved and if not create a new data table
19        Points  = 0,
20        Kills   = 0,
21        Deaths  = 0,
22    }
23    -- put their stats in the values and make the data visible, if you dont want the stats visible just change the name of 'leaderstats' to something like 'Statistics' or 'Stats'
24    points.Value    = data.Points
25    kills.Value         = data.Kills
26    deaths.Value    = data.Deaths
27    leaderstats.Parent = player
28    sessiondata[key] = data -- store their data in another table
29end
30local function onPlayerRemoving(player)
31    local leaderstats = player:WaitForChild('leaderstats')
32    local points, kills, deaths = leaderstats:WaitForChild('Points'), leaderstats:WaitForChild('Kills'), leaderstats:WaitForChild('Deaths')
33    local key = ('user_'..tostring(player.UserId)) -- key, unique to the player
34    local data = sessiondata[key] -- get their data from the sessiondata table
35    if data ~= nil then
36        -- put their stats in the table and save to the datastore
37        data.Points     = points.Value
38        data.Kills      = kills.Value
39        data.Deaths     = death.Value
40        local success, message = pcall(function() datastore:SetAsync(key, data) end) -- save the data
41        if (success == false) then -- if the data didn't save properly then print a warning to the console
42            warn('An error has occured: '..message)
43        end
44        sessondata[key] = nil -- remove the data, this isnt required but I like knowing that the table is as small as possible and only holds the data for all the players that are actually in the server.
45    end
46end
47--\\ Run Code //--
48for _, v in pairs (players:GetPlayers()) do onPlayerAdded(v) end -- if the script was restarted by console
49players.PlayerAdded:connect(onPlayerAdded) -- connect to the onPlayerAdded function when the event is fired
