This exercises is oriented towards columns of tabular data.
Given three columns of numeric data. Each column is a list of numbers or boolean false values.
The column length may vary from column to column
As an example, the first column col1 may be the list:
(1 5 #f 9 17)
This column may, together with two other columns, give the following table:
1 15 8 5 #f #f #f 0 11 9 6 17
Now, write a Scheme program supported by LAML that presents the table of columns. The table can be represented as the three individual columns. (And this is of course a little tricky, because HTML works with list of rows). #f values should be presented as blank table entries. In the fourth column, you should add the values in each row. When adding, the #f value and missing values (due to short columns) should be treated as 0.
Thus, a function call like (present-table table) should show this table.
