1. Using Kutools for Excel If you prefer to avoid VBA, the Kutools for Excel add-in offers a built-in feature to dynamically highlight the active row and column. It is more stable and user-friendly for non-technical users. 2. Limitations and Precautions VBA solutions do not work in protected worksheets without specific permissions. Furthermore, they can slightly slow down performance if the table is very large. It is therefore advisable to test on a sample before applying it on a large scale. 3. Conclusion and Recommendation For a slow and complex Excel table, the best approach is to use a VBA macro to dynamically highlight the active row. This significantly improves readability and data entry. If you prefer a no-code solution, Kutools is an excellent alternative.
