I didn't see your table there.
I made the table based off the data from the link.
Since it seems to be confusing you, let me explain the table to you.
The first column is the tax revenue for each year taken from my link.
The second column is the year.
The third column is the change in dollar amounts. I take the number from the current year and I subtract the number from the previous year.
The fourth column is where it gets tricky for some people. It is called the percent of change. It is determined by subtracting the current year from the previous year (column 3) and then dividing that number by the previous year. And what you get is a percent of change. For example, looking at 1988. The formula goes like this...(.909-.854)/.854, which simplifies to .055/.854, which comes out to .0644, which I then rounded to 6%, because .06 is the same thing as 6%.
I hope that helps.
