Description

In my application, I need to dynamically create the columns and then have the pull the columns from the state. However, when I do this, the code to update the row state does not work. Below is a simplified version, showing the issue. If you run this code, when you select the checkbox, the state does not get updated correctly.

If, however, I change BaseTable and set the columns= the actual array, then the selection process works.

Code that does not work
```
/* eslint-disable */
import React, { useState,useEffect } from 'react';
import BaseTable, { Column } from 'react-base-table';
import 'react-base-table/styles.css';

const MultiSelectTable = () => {
const [selectedRows, setSelectedRows] = useState([]);
const [columns, setColumns] = useState([])

useEffect(()=>{
setColumns(
[
{
key:"checkbox",
title:"",
width:50,
selectedRowKeys:{selectedRows},
cellRenderer:({ rowData }) => (
handleRowSelection({ rowData })}
/>
)}
,
{key:"name", dataKey:"name", title:"Name", width:200},
{key:"age", dataKey:"age", title:"Age", width:100}
]
)
},[])

const handleRowSelection = ({ rowData }) => {
const selectedRowKeys = [...selectedRows];
const rowIndex = selectedRowKeys.indexOf(rowData.id);

if (rowIndex !== -1) {
selectedRowKeys.splice(rowIndex, 1);
} else {
selectedRowKeys.push(rowData.id);
}

setSelectedRows(selectedRowKeys);
console.log(selectedRowKeys)
};

const data = [
{ id: 1, name: 'John Doe', age: 25 },
{ id: 2, name: 'Jane Smith', age: 30 },
{ id: 3, name: 'Bob Johnson', age: 35 },
// Add more data as needed
];

return (


);
};

export default MultiSelectTable;
```

Code that works:

```
/* eslint-disable */
import React, { useState,useEffect } from 'react';
import BaseTable, { Column } from 'react-base-table';
import 'react-base-table/styles.css';

const MultiSelectTable = () => {
const [selectedRows, setSelectedRows] = useState([]);

const handleRowSelection = ({ rowData }) => {
const selectedRowKeys = [...selectedRows];
const rowIndex = selectedRowKeys.indexOf(rowData.id);

if (rowIndex !== -1) {
selectedRowKeys.splice(rowIndex, 1);
} else {
selectedRowKeys.push(rowData.id);
}

setSelectedRows(selectedRowKeys);
console.log(selectedRowKeys)
};

const columns= [
{
key:"checkbox",
title:"",
width:50,
selectedRowKeys:{selectedRows},
cellRenderer:({ rowData }) => (
handleRowSelection({ rowData })}
/>
)}
,
{key:"name", dataKey:"name", title:"Name", width:200},
{key:"age", dataKey:"age", title:"Age", width:100}
]

const data = [
{ id: 1, name: 'John Doe', age: 25 },
{ id: 2, name: 'Jane Smith', age: 30 },
{ id: 3, name: 'Bob Johnson', age: 35 },
// Add more data as needed
];

return (


);
};

export default MultiSelectTable;

```

How can I load the columsn dynamically into state but still have the selection of rows work?

Research direction

Reproduce the provided MultiSelectTable example, comparing columns created in useEffect with the inline columns array passed to BaseTable. Trace how the state-backed columns and cellRenderer observe selectedRows, then verify that selecting a checkbox updates both selectedRows and the rendered checkbox state.
