Too many unknowns.
What do the specs for your tablet show what USB drives it can support? 2.0, 3.0, FAT, exFAT?
What OS is your tablet running? Linux, Windows, XP, Vista, 7, 8 10?
What are the specs for your OTG drive? 32GB, 64GB, 128GB, USB 2.0, 3.0?
When it worked in the PC did you format it? The fact that it worked in the PC indicates the OTG drive is OK, the problem is in the tablet.
