@sandhya ma'am, please tell me if this looks correct to you.The first column in the middlewhy this is "left" panel again? Now "middle" panel is being explained, i guess!!the middle panel is divided in 3 sub-columns, and that is being explained hereyes, it could be written as 1st column in middle panel..can I write it as first sub column in middle panel instead?have made the correctionyou can't say it as sub- column, because you have mentioned it earlier as "panel" divided into 3 columns. columns are not divided further into sub-columns. So, it is a column, and not a sub-column. '''panel''' shows the serial number.

only a column can be divided into sub-columns. sub-columns don't appear without having columns...this is my opinion...period.The middle '''panel''' is divided into 3 columns.

@sandhya ma'am, please tell me if this looks correct to you.The first column in the middlewhy this is "left" panel again? Now "middle" panel is being explained, i guess!!the middle panel is divided in 3 sub-columns, and that is being explained hereyes, it could be written as 1st column in middle panel..can I write it as first sub column in middle panel instead?have made the correctionyou can't say it as sub- column, because you have mentioned it earlier as "panel" divided into 3 columns. columns are not divided further into sub-columns. So, it is a column, and not a sub-column. '''panel''' shows the serial number.

The second column in the middle '''panel''' shows the reference '''ID''' of the '''component'''s used in the '''schematic'''.

only a column can be divided into sub-columns. sub-columns don't appear without having columns...this is my opinion...period.The middle '''panel''' is divided into 3 columns.

@sandhya ma'am, please tell me if this looks correct to you.The first column in the middlewhy this is "left" panel again? Now "middle" panel is being explained, i guess!!the middle panel is divided in 3 sub-columns, and that is being explained hereyes, it could be written as 1st column in middle panel..can I write it as first sub column in middle panel instead?have made the correctionyou can't say it as sub- column, because you have mentioned it earlier as "panel" divided into 3 columns. columns are not divided further into sub-columns. So, it is a column, and not a sub-column. '''panel''' shows the serial number.

The second column in the middle '''panel''' shows the reference '''ID''' of the '''component'''s used in the '''schematic'''. 

The third column in the middle panel shows the values of the corresponding components, if any'''.'''
