I'm having trouble centering a button in a td.
This is probably a simple CSS issue, but the app is using bootstrap, AngularJS, AngularJS-ui-bootstrap, and ngTable. I've included all of these components in my plunkr.
I'm trying to set "horizontal-align: middle" on the td with the button, but that doesn't seem to get applied. The button still leans to the left side of the cell.
