我将NSAttributedString插入到NSTableView中,并根据它的内容将属性添加到其样式字典中。NSAttributedString删除线不会绘制整个文本的长度

- (id)tableView:(NSTableView *)aTableView objectValueForTableColumn:(NSTableColumn *)aTableColumn row:(NSInteger)rowIndex { 


NSAttributedString *theValue; 
NSMutableDictionary *attributes = [[NSMutableDictionary alloc] init]; 
[attributes setObject:[NSFont systemFontOfSize:11] forKey:NSFontAttributeName]; 
currentObject = [ticketsDataSource objectAtIndex:rowIndex]; 

if ([[currentObject valueForKey:aTableColumn.identifier] isKindOfClass:([NSString class])]) { 

    NSString *currentValue = [currentObject valueForKey:aTableColumn.identifier]; 

    if ([currentValue isEqualToString:@"resolved"]) { 

     [attributes setObject:[NSColor colorWithCalibratedRed:0.344 green:0.619 blue:0.000 alpha:1.000] forKey:NSForegroundColorAttributeName]; 

    } 

    if ([previousValue isEqualToString:@"resolved"]) { 

     [attributes setObject:[NSNumber numberWithInteger:NSUnderlinePatternSolid | NSUnderlineStyleSingle] forKey:NSStrikethroughStyleAttributeName]; 
    } 

    theValue = [[NSAttributedString alloc] initWithString:currentValue attributes:attributes]; 
    previousValue = currentValue; 

} 

正如你所看到的,基本上会发生什么是当它写了一个名为“解决”字符串,它知道第二天列,这是标题列,得到了删除线。它工作得很好,但无论出于何种原因,删除线不会覆盖整个文本!

这里是一个形象:

这到底是怎么回事?

还有另一个古怪的层次支持。所以我把它关掉:(
