How do I transfer videos from an SD card to my Android Google Tablet

How do I transfer videos from an SD card to my Android Google Tablet. I uploaded some videos from my laptop to an SD card and placed the SD card in an integral SDHC reader and plugged this into the Tablet and I can play the videos on Google Play Movies but if I unplug the reader the videos disappear. I want them permanently on my Tablet without having to plug in the reader every time I want to watch the videos. Can someone tell me how to do this?
I have an Android Google Tablet China Telecom Infotmic Txz799D.

The easiest way would hve been to copy them straight from the PC to the tablet, rather than to an SD card.
i.e. connect the tablet to your computer via USB
Open Explorer and the tablet should appear as an external drive (in the same way that the SD card did). Then just copy them across.

I have tried that but the Android Google Tablet does not recognise the USB cable

In that case, can't you just transfer the data from the sd card to the Tablet's memory.
