  <pre><code>const columns = [
       {
           accessor: &quot;id&quot;,
           show: false,
       },
       {
          Header: &quot;Username&quot;,
          id: &quot;username&quot;,
          accessor: &quot;username&quot;,
          Cell: this.usernameFormatter,
          enableRowSpan: true
       }
  ]
            
  &lt;ReactTable
      data={this.state.users}
      filterable={true}
      columns={columns}
      defaultPageSize={18}
      getTdProps={(state, rowInfo, column) =&gt; {
          const index = rowInfo ? rowInfo.index : -1;
          return {
              onClick: (e, handleOriginal) =&gt; {
                  if (column.Header === undefined) {
                      handleOriginal();
                  } else {
                      if (rowInfo !== undefined) {
                          this.selectedRow = index;
                          this.onRowSelect(rowInfo.original.id);
                      }
                  }
              },
          };
