Data about the planets of our solar system(Planetary facts taken from Nasa's Planetary Fact Sheet - Metric).

Here is a link to my topic for your reference,

  Name Mass (1024kg) Diameter (km) Density (kg/m3) Gravity (m/s2)>/th> Length of day (hours) Distance from Sun (106km) Mean temperature (°C) Number of moons Notes
Terrestrial planets Mercury 0.330 4879 5427 3.7 4222.6 57.9 167 0 Closest to the Sun
Venus 4.87 12,104 5243 8.9 2802.0 108.2 464 0
Earth 5.97 12,756 5514 9.8 24.0 149.6 15 1 Our world
Mars 0.642 6,792 3933 3.7 24.7 227.9 -65 2 The red planet
Jovian Planets Gas Giants Jupiter 1898 142,984 1326 23.1 9.9 778.6 -110 67 The largest planet
Saturn 568 120,536 687 9.0 10.7 1433.5 -140 62
Ice giants Uranus 86.8 51,118 1271 8.7 17.2 2872.5 -195 27
Neptune 102 49,528 1638 11.0 16.1 4495.1 -200 14
Dwarf planets Pluto 0.0146 2,370 2095 0.7 153.3 5906.4 -225 5 Declassified as a planet in 2006, but this remains controversial.

You just need to insert an empty <th>(table header) that occupies 2 columns in <thead> like: <th colspan="2">&nbsp;</th>

and therefore making the <th>Terrestrial planets</th> occupies 2 columns too (e.g., <th colspan="2" rowspan="4">Terrestrial planets</th>).

I hope this helps!

Thank you so much @allanjramospaixao.
I will apply that.

Good Day…!!
