Table Reading & Lookups
Why this is here
Six small exercises, all built on the same underlying skill: read a table correctly before you act on it. Row counts and values regenerate on every load and Reset, so nothing here can be solved by hardcoding a number you saw once.
1. Count the rows
2. Read the last row
3. Does it contain this value?
4. Grid lookup
A weekly meeting room schedule — read the grid to answer the question below it.
5. Criteria-driven dropdown
6. Edit the right row
| First name | Last name | Action |
