Frozen Columns support for Column Groups

[MPanahandeh]

Something goes wrong with the column Name in my data grid when I use Frozen specification with Column Grouping. I have the first column repeated, but If I disable frozen config in my table it will be fine.

Code:

Please provide a test code that we can run.

I added just two rows of mock data to the github link I had provided.
https://github.com/MPanahandeh/time-tracker
$ npm install
$ npm start
If you comment out lines like what I did in data-grid.jsx, grid works normally but no more frozen column

 render() {
    this.initialColumns()
    const headerGroup = DateHeader(this.frozenWidth, this.props.dateArray)
    return (
      <DataTable
        sortable
        // header='Time tracking'
        value={this.props.model}
        scrollable
        scrollHeight='580px'
        style={{
          marginTop: '30px',
          width: `${this.tableWidth}px`,
          fontSize: '15px',
        }}
        // frozenWidth={`${this.frozenWidth}px`}
        // unfrozenWidth={`${this.tableWidth - this.frozenWidth}px`}
        // headerColumnGroup={DateHeader(this.props.dateArray)}
        headerColumnGroup={headerGroup}
      >
        {this.columns}
      </DataTable>
    )
  }

and

  this.columns.unshift(
      <Column
        sortable
        key={0}
        body={NameCell}
        field='name'
        header='Name'
        style={{ width: this.frozenWidth }}
        // frozen
      />,
    )

We did this for PrimeNG lately and need to do some changes for PrimeReact as well, will do it for 1.0.2.

Added headerColumnGroup and footerColumnGroup properties

render() {
        let headerGroup = <ColumnGroup>
                            <Row>
                                <Column header="Sale Rate" colSpan={4} />
                            </Row>
                            <Row>
                                <Column header="Sales" colSpan={2} />
                                <Column header="Profits" colSpan={2} />
                            </Row>
                            <Row>
                                <Column header="Last Year" field="lastYearSale" sortable={true}/>

                            </Row>
                        </ColumnGroup>;

       let footerGroup = <ColumnGroup>
                            <Row>
                                <Column footer="Totals:" colSpan={3} />
                                <Column footer="$506,202" />

     let frozenHeaderColumnGroup = <ColumnGroup>

        return (

                    <DataTable value={this.state.sales} headerColumnGroup={headerGroup} scrollable={true} frozenHeaderColumnGroup={frozenHeaderColumnGroup}
                                                        footerColumnGroup={footerGroup} 
                                                        scrollHeight="200px" frozenWidth="200px" unfrozenWidth="600px">                        
                        <Column field="brand" frozen={true} />
                        <Column field="lastYearSale" />
                        <Column field="thisYearSale" sortable={true}/>
                        <Column field="lastYearProfit" sortable={true}/>
                        <Column field="thisYearProfit" sortable={true}/>
                    </DataTable>
                </div>
            </div>
        );
    }

This seems to be broken on PrimeReact 6.

The above example produces

Any suggestion?

Hi @claudv,

Thanks a lot for your report. On 7.0, I'll reimplement scrollable DataTables like in primevue;
https://primefaces.org/primevue/showcase/#/datatable/scroll

If the problem persists after 7.0, please reopen this issue.

Best Regards,

Hi, it looks like still not working or got broken on newer versions
I'm using primereact 10.8.2 and react 18.2.0
Here is an example of what I am trying to do ( I set many columns to demonstrate the issue )
