I have multiple buttons that will reading the same tag but I want a power table to update and read the tag data when the buttons are clicked. I'm new to ignition and unsure how to start.

If you have time i would start by completing the credential courses, specifically the ones related to Vision.

What you'll need is an actionPerformed script on your button and use the [system.tag.readBlocking()](https://docs.inductiveautomation.com/docs/8.1/appendix/scripting-functions/system-tag/system-tag-readBlocking) (Or [system.tag.read()](https://docs.inductiveautomation.com/docs/7.9/appendix/scripting-functions/system-tag/system-tag-read) if your ignition version is prior to 8.0.) and then use te results to update the table's dataset with [system.dataset.setValue()](https://docs.inductiveautomation.com/docs/8.1/appendix/scripting-functions/system-dataset/system-dataset-setValue)  
But to start on your objective you can take a look at the Vision Component Scripting videos.
