How do I ensure my matrix indexing formulas adjust correctly when rows or columns are inserted or deleted within the indexed range?

To ensure your matrix indexing formulas adjust correctly when rows or columns are inserted or deleted, avoid hardcoding row and column numbers. Instead, use formulas like `ROW()` or `COLUMN()` in conjunction with `OFFSET` or `INDEX` and `MATCH`. Alternatively, if your data is in a structured Excel Table, its references (e.g., `TableName[ColumnName]`) automatically update when the table is modified.
