title: jobj_col
---

The `jobj_col` method creates a column containing Java objects.

> [!NOTE]
> This method is commonly used with [`new_table`](./newTable.md) to create tables.

> [!CAUTION]
> The `jobj_col` method is significantly slower than other methods that create columns. When creating a column with data of one type, use the corresponding specialized method (e.g., for ints, use [`int_col`](./intCol.md)).

## Syntax

```python syntax
jobj_col(name: str, data: Sequence[Any]) -> InputColumn
```

## Parameters

<ParamTable>
<Param name="name" type="str">

The name of the new column.

</Param>
<Param name="data" type="Sequence[Any]">

The column values.

</Param>
</ParamTable>

## Returns

An [`InputColumn`](/core/pydoc/code/deephaven.column.html#deephaven.column.InputColumn).

## Example

The following examples use [`new_table`](./newTable.md) to create a table with a single column of Java objects named `Values`.

```python
from deephaven import new_table
from deephaven.column import jobj_col

result = new_table([jobj_col("Values", ["a", 1, -5.5])])
```
