Delete rows from this table.
This can be used to delete a single row, many rows, all rows, or
sometimes no rows (if your predicate matches nothing).
**`Examples`**
```ts
const con = await lancedb.connect("./.lancedb")
const data = [
{id: 1, vector: [1, 2]},
{id: 2, vector: [3, 4]},
{id: 3, vector: [5, 6]},
];
const tbl = await con.createTable("my_table", data)
await tbl.delete("id = 2")
await tbl.countRows() // Returns 2
```
If you have a list of values to delete, you can combine them into a
stringified list and use the `IN` operator:
```ts
const to_remove = [1, 5];
await tbl.delete(`id IN (${to_remove.join(",")})`)
await tbl.countRows() // Returns 1
```
##### Parameters
| Name | Type | Description |
| :------ | :------ | :------ |
| `filter` | `string` | A filter in the same format used by a sql WHERE clause. |
| `filter` | `string` | A filter in the same format used by a sql WHERE clause. The filter must not be empty. |
