```I have a matica simulation that generates a Table. Currently it prints in at
the bottom of the notebook and then I copy and paste it into a text file.

below is the code that generates the Table.

**************************************************
PD2mnax0[PD2u_] := 1/(1 + Exp[-(PD2u + 24.7)/5.29]);
PD2hnax0[PD2u_] := 1/(1 + Exp[(PD2u + 48.9)/5.18]);
PD2mk10x[PD2u_] := 1/(1 + Exp[-(PD2u + 14.2)/11.8]);
PD2taumnax[PD2u_] := 1.32 - 1.26/(1 + Exp[-(PD2u + 120)/25]);
PD2tauhnax[
PD2u_] := (0.67/(1 + Exp[-(PD2u + 62.9)/10]))*(1.5 +
1/(1 + Exp[(PD2u + 34.9)/3.6]));
PD2taumk1[PD2u_] := 7.2 - 6.4/(1 + Exp[-(PD2u + 28.3)/19.2]);

solution = NDSolve[{

PD2mnax'[
t] == (PD2mnax0[PD2z[t]] - PD2mnax[t])*(1/PD2taumnax[PD2z[t]]),
PD2mnax == PD2mnax0[-80]*(1/PD2taumnax[-80]),
PD2hnax'[
t] == (PD2hnax0[PD2z[t]] - PD2hnax[t])*(1/PD2tauhnax[PD2z[t]]),
PD2hnax == PD2hnax0[-80]*(1/PD2tauhnax[-80]),
PD2mkx'[t] == (PD2mk10x[PD2z[t]] - PD2mkx[t])*(1/PD2taumk1[PD2z[t]]),
PD2mkx == PD2mk10x[-80]*(1/PD2taumk1[-80]), PD2z'[t] == (-1*(0
+ 1*1100*(PD2mnax[t]^3)*PD2hnax[t]*(PD2z[t] - 50)
+ 1*150*(PD2mkx[t]^4)*(PD2z[t] + 80)
+ 1*0.00081*(PD2z[t] + 50)
)
*(1/6)),
PD2z == -80

},

{PD2z, PD2mnax, PD2hnax, PD2mkx}, {t, 0, time}, Method -> Automatic,
MaxSteps -> Infinity];

mkw = Table[0, {time - 1}];

For[w = 1, w < (time), mkw[[w]] = PD2z[w] /. solution; w++];

mkw
