In ConTeXt 2017.05.15 (shipped with TexLive 2017), the second column is formatted as text rather than math. The result gives ‘slope_B’ rather than placing B as a subscript.
Online and with 2016.05.17 (shipped with TexLive 2016), the second column is formatted correctly as math. so no problem then ... you can install context minimals alongside tex
