When using the xlnt library, I encounter an xlnt::individual_attribute exception when trying to copy cell styles using the following code:

[qwwjh21]

for (auto col = 1; col <= ws.highest_column().index; ++col)
{
xlnt::cell sourceCell = ws.cell(col, copyRow);
xlnt::cell targetCell = ws.cell(col, curRow);
xlnt::style sourceStyle = sourceCell.style();

// Copy the source cell style
targetCell.border(sourceCell.border());
targetCell.font(sourceCell.font());
targetCell.alignment(sourceStyle.alignment());

// Clear the target cell style
targetCell.clear_style();

// Attempt to set the target cell style
targetCell.style(sourceStyle);  // This line throws the xlnt::individual_attribute exception

}

Error Message:
xlnt::individual_attribute

Expected Behavior:
I expect to be able to copy the complete style of the source cell to the target cell using targetCell.style(sourceStyle) without encountering any exceptions.

Actual Behavior:
The call to targetCell.style(sourceStyle) throws the xlnt::individual_attribute exception, causing the style copying to fail.
