The net ionic equation is SO42- + Ca2+ CaSO4.
Ca2+(aq) + SO42-(aq)- --> CaSO4(s) is the net ionic equation.

CaSO4 is an ionic compound because it contains two ions namely CA2+ and SO42-.
2Na+(aq) + SO42-(aq) + Ca2+(aq) + 2Cl-(aq) CaSO4(s) + 2Na+(aq) + 2Cl-(aq)
2H+ + SO42- + Ca2+ + 21 > CaSO4 + 2H+ + 21-
Ca2+ + 2OH- + 2H+ + SO42- -------> 2H2O + Ca2+ + So42- 2OH- + 2H+ -------> 2H2O
H+ and I- are the spectator ions.
The ion-ion bond in CaSO4 is stronger than in NaCl because of the higher charges on the cation and anion. Be careful in making this argument. The ion-dipole forces of Ca2+ -H2O and SO42- - H2O might actually be stronger than that of Na+ -H2O and Cl- -H2O due to the high charges on Ca2+ and SO42- . However the strengths of the ions-dipole interactions do not match (or exceed) the strength of the Ca2+ -SO42- ionic bond.
