Hi Ruchi,
I hope you would be using Image control as template to load the image in table column.
Use a formatter for Image 'src' property, where you can provide the model property path of 'Column A'.
Will this sample help? Plunker
In the above example, if 'Out of Tolerance' column value is true, then a red color image loaded, if it is false, then a green color image loaded.

Sai Vellanki.
