Auto duplicate changes made in one column of one worksheet to another worksheet

I have a spreadsheet that has 2 worksheets. The first has a list of items in column A5 -A135 and sheet two lists expenses for those items. I would like to have what ever changes ( format, color fill, adding additional rows, etc) be automatically duplicated to column A5-A135 etc on worksheet 2.
The column is divided into section categories with description headers at each section so occasionally I need to add a row inside a section category when I run out of space.
Any help would be greatly appreciated.

Can you please attach a copy of your spreadsheet in xls or xlsx format.
Please remove or change any sensitive information.

Thank you for your response. I am sending a sample test workbook for you to see. I hope you understand what I need. Please feel free to ask questions.

Please see attached.
It may not be exactly what you are looking for but it is a "workaround" that I have used many times.
On the Items Sheet in cell A4 click Items for Items and Cost for cost (everything is now on the same sheet and some cells are linked).
Let me know if it is of any use to you.

Thank you very much. I like this. Now how do I input this into my current workbook?

I have attached another copy of my workbook but have added to the Cost Sheet a "step by step guide" which hopefully you will be able to follow.
Any problems or queries let me know.
