# Description
Fixes a couple panics:
```
> {} | inspect
Error: x Main thread panicked.
|-> at crates/nu-command/src/debug/inspect_table.rs:87:15
`-> attempt to divide by zero
```
```
> {} | explore
# see an empty column, press Down
Error: x Main thread panicked.
|-> at crates/nu-explore/src/views/cursor/mod.rs:39:9
`-> attempt to subtract with overflow
```
# User-Facing Changes
`{} | inspect` now outputs an empty table:
```
╭─────────────┬────────╮
│ description │ record │
├─────────────┴────────┤
│ │
├──────────────────────┤
```
`{} | explore` opens the help menu.
Both match the empty list behavior.
# Tests
I'm not sure how to test `explore`, as it waits for interaction.
