The first column named half life elapsed tells  us the the number of half life that that is completed. Half life is the time taken for an element to reduce or decay into half of its initial amount.

The fraction remaining column gives the amount of sample that is left behind  after the half life particular number of half life has completed.  similarly the percentage remaining column gives the amount of sample in percentage. For example, the 5th row tells us that after 4 half life is over \frac{1}{16} th of the sample remained. In percentage it is 6.25%
