The left column gives the name of the problem.

The third column gives the change, in percentage points, of pupils reading at or above grade level from the previous year.

The second column gives conditions for which a solution is valid.

The last column gives the percentage change from the previous year in the proportion of students reading at or above grade level.

And the column I was writing gave me a lot of time to think about it.

The far left column labeled "Roll" will give the number of the vote.

The 1989 column gives the estimated population as of July 1.

The 1980 column gives the population according to the 1980 census.

The column gave them what food they had left, and rode on.

At the very least, a column gives readers some insight into how mistakes happen.
