Are there any best practices for adjusting cell widths in Excel to prevent display issues like ###########?

When the content of a cell in Excel is too wide for the column width, Excel displays a series of pound signs (###########) to indicate that the content is not fully visible. To prevent this issue, adjust the cell width to accommodate the content. This can be done manually by dragging the column boundary or automatically by double-clicking the boundary to fit the widest content in the column.

// Adjust column width in Excel to prevent display issues like ###########
$objPHPExcel->getActiveSheet()->getColumnDimension('A')->setAutoSize(true);
