Hi Hasan
No, the values in the table were not hand written. The video creator used Mechanical APDL interactively to create the equation and evaluate it over a time range. Then exported it out - the exported APDL text version was then copy/pasted to the WB Mechanical Commands Object. They just did not show those steps.
See for example this Forum discussion:
