Investigate the possible solution for HTML Comparison view for tables

There are several scenarios that the Table comparison is not working as expected:

Original table for Scenarios 1,2,3,4

Scenario 1:

Create a new doc and Add a table(3x2) in Content part with rich text editor
fill all the cells of the table
Save and Publish
Delete the content in the cell of first row - second column
Save changes

Expected: Diff view shows deleted content with red in the cell of first row - second column
Actual: 3rd column added to the table and the deleted content is shown with red in that column while the cell in first row - second column has green like it is newly added.

Scenario 2: 

Create a new doc and Add a table(3x2) in Content part with rich text editor
fill all the cells of  the table
Save and Publish
Copy the first row and paste it as second row (Still 3x2 table)
Save changes

Expected: Newly added row's content will be green 

 

Scenario 3:

Create a new doc and Add a table(3x2) in Content part with rich text editor
fill all the cells of  the table
Save and Publish
Delete the 3rd row completely(2x2))
Save changes

Expected: 3rd row should be red
Actual: there is no 3rd row, there are 2 new columns and deleted content is shown in the 2nd and 4th columns

 

 

Scenario 4:

Create a new doc and Add a table(3x2) in Content part with rich text editor
fill all the cells of  the table
Save and Publish
Change the content in the cell(first row first column) (ex: change "nert" to "new")
Save changes

Expected: nertw
Actual: First row first column is red, Third row second column green there is 3rd column with the word new
