SQL Server How to add trigger to create same column in another table

Question

I'm trying to figure out how to write a trigger that will add a newly created column to another table.

Situation: I have dbo.tableA and dbo.tableA_Archive tables.

When I add a column to dbo.TableA using this T-SQL:

ALTER TABLE dbo.TableA 
    ADD [Column72] INT NULL

I need the trigger to add the same column to the dbo.TableA_Archive table as well.

I have not been able to find any examples that come close to doing this.

Since several commenters decided to just rag on me, and only @Bogdan Sahlean posted any thing of relevance, I'd give them credit, but they didn't post it as an answer.

Here is the final solution I came up with based on their guidance.

CREATE OR ALTER TRIGGER AlterTable
ON DATABASE
AFTER ALTER_TABLE
AS
BEGIN
    DECLARE
        @lv_xml_EventData XML,
        @lv_vc_SQLCMD VARCHAR(MAX)
    SET @lv_xml_EventData = EVENTDATA()
    IF @lv_xml_EventData.value('(EVENT_INSTANCE/ObjectType)[1]','VARCHAR(200)') = 'TABLE'
    BEGIN
        DECLARE
            @lv_vc_Table_Name VARCHAR(200) = @lv_xml_EventData.value('(EVENT_INSTANCE/ObjectName)[1]','VARCHAR(200)')
            
        IF @lv_vc_Table_Name = 'TableA'
        BEGIN
            SET @lv_vc_SQLCMD = @lv_xml_EventData.value('(EVENT_INSTANCE/TSQLCommand/CommandText)[1]','VARCHAR(MAX)')
            SET @lv_vc_SQLCMD = REPLACE(@lv_vc_SQLCMD,'TableA','TableA_Archive')
            BEGIN TRY
                EXEC (@lv_vc_SQLCMD)
            END TRY
            BEGIN CATCH
                THROW;
                ROLLBACK
            END CATCH
        END
    END
END

Now I know there are probably better ways to do this, but it does answer my question, and meet my needs.
