Highlight coordinates / positions

Hi everybody,
I hope this message finds you well. I
In my current project, I am working with a main table in Excel that represents fabric measurements. Specifically, the A column denotes the length, ranging from 1 to 100 meters (each row representing 1 meter), while the first row indicates the width, spanning from 0 to 150 cm (with 5 columns of 30 cm each).
Additionally, I maintain a separate defect table within the same Excel file. This defect table contains information about various defects found in the fabric, including the defect name, the meter at which it is present, and its position from the left selvage.
I need to highlight corresponding cell in the main table (surely between the range) based on the defect information stored in the defect table.
Could you kindly provide guidance or assistance on how to achieve this in Excel? Any insights or recommendations would be greatly appreciated.
Thank you for your time and support.roll.xlsx Screenshot_2.png
