No you cannot. 63 is the maximum number of columns for a table created in Word. If you require more than that, use Excel instead.
45 columns is the maximum allowed, but that is far more than you need or is practical to use.
When you are defining the amounts of rows and columns for a table, Word allows to have one row and one column, in other words a single cell. So that is the absolute minimum. You may not regard that as being a table, so you can have two rows and one column or one row and two columns. You can have anything above that. Word usually suggests five columns and two rows as a default, but that can be changed.

No, 63 is not in the 4x table. The multiples of 4 are obtained by multiplying 4 by whole numbers (0, 1, 2, 3, etc.), resulting in numbers like 0, 4, 8, 12, and so on. Since 63 cannot be evenly divided by 4, it does not appear in the 4x table.
