Remove a table item when its Index is unknown

[BioHazard]

Will just leave this one up here for anyone interested.

While trying to figure out how to remove a table item when its Index number is dynamic (ie. unknown), I stumbled across a custom function to employ with Table.Remove which makes this possible.

Custom function: TableFindIndex.
Example useage attached.
Adapted from: here

re-post,

Sorry, some superfluos naming conventions in above example. Is functionally correct - but inconsistent variable naming may cause confusion.

Function code should read:

function TableFindIndex (tData, tValue)
    for index, value in pairs(tData) do
        if value == tValue then
            return index
        end
    end
end

Example useage code has been adjusted accordingly. Corrected APZ now re-upped and attached below.

LOL, an edit button on this board would be a nice thing wouldn't it?

Or,

...it can also be done without the custom function, by using the String.Find command in a for/do loop. Like this:

tData = {
    "Japan",
    "Russia",  -- here is our table of data
    "USA"
};

tValue = "Russia";  -- here is our table Value (whose Index number we assume is unknown)

Debug.Clear();
Debug.ShowWindow(true);

for i, v in pairs (tData) do -- loop through table (tData)    
    if String.Find(v, tValue, 1, false) >0 then -- if "Russia" (tValue) is found, returns number >0 
                                                -- and catches tValue's Index number (stored in 'i').        
        Table.Remove(tData, i) -- now we can use Table.Remove command in normal way                
        
        for i, v in pairs (tData) do -- loop through newly modified table
            Debug.Print(v .. "\r\n"); -- and print remaining Values        
        end
    end
end

Or,

...we can go even simpler, by just employing the value-matching method originally expressed in the custom function above. Like this:

tData = {
    "Japan",
    "Russia",
    "USA"
};

tValue = "Russia";

Debug.Clear();
Debug.ShowWindow(true);

for i, v in pairs (tData) do    
    if v == tValue then        
        Table.Remove(tData, i)            
        for i, v in pairs (tData) do
            Debug.Print(v .. "\r\n");    
        end
    end
end

Probably should've just posted this one first - now that I've managed to confuse everybody!
This board needs an EDIT button. Hint, hint!
