Designing a hash function for storing strings in a hash table of size 10 involves a few steps. Here's a simple example:

1. **Hash Function Design**: A simple hash function can be designed by taking the ASCII value of the characters in the string, summing them up, and then taking the modulus of the sum by the size of the hash table. In Python, this can be implemented as follows:

```python
def hash_function(key):
return sum(ord(c) for c in key) % 10
```

2. **Handling Collisions**: There are several ways to handle collisions, but one common method is separate chaining. In separate chaining, each slot in the hash table points to a linked list of entries that have hashed to the same slot.

3. **Inserting Names**: To insert names into the hash table, you would first use the hash function to determine the appropriate slot, and then add the name to the linked list at that slot. Here's an example with three names:

```python
hash_table = [[] for _ in range(10)] # Initialize an empty hash table

def insert(hash_table, key):
hash_key = hash_function(key)
hash_table[hash_key].append(key)

names = ['Alice', 'Bob', 'Charlie']
for name in names:
insert(hash_table, name)
```

After running this code, the hash table might look something like this (assuming the hash function distributes the names evenly):

```python
[['Alice'], [], [], [], ['Bob'], [], [], [], [], ['Charlie']]
```

In this example, 'Alice' hashes to slot 0, 'Bob' hashes to slot 4, and 'Charlie' hashes to slot 9. Since there are no collisions in this example, each slot contains a single-element list. If there were collisions, the lists would contain multiple elements.
