The equation should also account for the alpha and beta values put into cells H2 and H4

Make me an Excel table that can solve TAF, S, T, and error (Show me all formulas) Also cell A1 is the one that says "period". I just want to put in actual values for each period and the rest to fill itself out with the answers. Thank you! \begin{tabular}{|c|c|c|} \hline & G & H \\ \hline 1 & Smoothing constraints & \\ 2 & Alpha = & 0.3 \\ 3 & & \\ 4 & Beta = & 0.4 \\ \hline 5 & & \\ \hline 6 & & \\ 7 & & \\ 8 & & \\ \hline 9 & & \\ \hline 10 & & \\ \hline 11 & & \\ \hline \end{tabular}
