篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了CSS 如何实现一行表格的横向颜色渐变相关的知识，希望对你有一定的参考价值。
<table>
<tr>
<td>1</td>
<td>2</td>
</tr>
<tr>
<td>3</td>
<td>4</td>
</tr>
</table>
如何实现 <tr> <td>1</td> <td>2</td> </tr> 这一行背景色渐变，不是单独一个格子内的颜色变化，其他行不变。
table tr
background-color:#FF0000;
#aaafilter : progid:DXImageTransform.Microsoft.Alpha(startX=0, startY=0, finishX=100, finishY=100,style=1,opacity=100,finishOpacity=50);
#bbbfilter : progid:DXImageTransform.Microsoft.Alpha(startX=0, startY=0, finishX=100, finishY=100,style=1,opacity=50,finishOpacity=0);
</style>
</head>
<body>
<table border="0" cellpadding="0" cellspacing="0">
<div>
<tr>
<td id="aaa">111111</td>
<td id="bbb">222222</td>
</tr>
</div>
<tr>
<td>3</td>
<td>4</td>
</tr>
</table>
</body>
简单的说应该没有直接的方法能实现这个功能
只能变相实现~~ 如上方法让每个TD渐变 然后只要让颜色衔接上 看起来就像
每个TR颜色渐变了~~本回答被提问者采纳 参考技术B 那你只能用图片做背景了。
如何在 iOS 中使用 CAGradientLayer 在 UITableViewCell 中设置多个渐变颜色？
【中文标题】如何在 iOS 中使用 CAGradientLayer 在 UITableViewCell 中设置多个渐变颜色？【英文标题】：How to set multiple gradient colour in UITableViewCell using CAGradientLayer in iOS? 【发布时间】：2015-05-27 09:53:26 【问题描述】：我想设置多个渐变颜色，每一行都有唯一的渐变颜色，如下图所示：
我想要实现的是第一张图片，我能够实现的是第二张
我为我能够实现的目标编写的代码是
BackgroundLayer.h
+(CAGradientLayer*) CustomHorBlack;
BackgroundLayer.m
+ (CAGradientLayer*) CustomHorBlack
UIColor *colorOne = [UIColor colorWithRed:(0.0) green:(0.0 ) blue:(0.0) alpha:0.1];
UIColor *colorTwo = [UIColor colorWithRed:(0.0) green:(0.0 ) blue:(0.0) alpha:0.2];
UIColor *colorThree = [UIColor colorWithRed:(0.0) green:(0.0 ) blue:(0.0) alpha:0.3];
UIColor *colorFour = [UIColor colorWithRed:(0.0) green:(0.0 ) blue:(0.0) alpha:0.4];
UIColor *colorFive = [UIColor colorWithRed:(0.0) green:(0.0 ) blue:(0.0) alpha:0.5];
UIColor *colorSix = [UIColor colorWithRed:(0.0) green:(0.0 ) blue:(0.0) alpha:0.6];
NSArray *colors = [NSArray arrayWithObjects:(id)colorOne.CGColor, colorTwo.CGColor,colorThree.CGColor,colorFour.CGColor, colorFive.CGColor,colorSix.CGColor, nil];
CAGradientLayer *headerLayer = [CAGradientLayer layer];
headerLayer.colors = colors;
[headerLayer setStartPoint:CGPointMake(0.0, 0.5)];
[headerLayer setEndPoint:CGPointMake(1.0, 0.5)];
return headerLayer;
TableCell.m
-(void)awakeFromNib
[[[self contentView] superview] setClipsToBounds:YES];
CAGradientLayer *bgLayer = [BackgroundLayer CustomHorBlack];
// bgLayer.frame = self.contentView.bounds;
bgLayer.frame = CGRectMake(-7, 0, [Util window_width], 72);
if ([Util isiPhone6])
bgLayer.frame = CGRectMake(-7, 0, [Util window_width], 84);
else if ([Util isiPhone6PlusDevice])
bgLayer.frame = CGRectMake(-7, 0, [Util window_width], 93);
[self.CatImageView.layer insertSublayer:bgLayer atIndex:0];
我为想要实现的目标编写的代码是，但没有找到我想要的目标
-(void)awakeFromNib
if (!checkVariable)
variable=0;
checkVariable=TRUE;
[[[self contentView] superview] setClipsToBounds:YES];
CAGradientLayer *bgLayer;
//= [BackgroundLayer CustomHorBlack];
for(variable = 0; variable < 10; variable++)
switch(variable)
case 0:
bgLayer = [BackgroundLayer CategoryHealthButy];
//variable = variable + 1;
break;
case 1:
bgLayer = [BackgroundLayer CategoryClothing];
// variable = variable + 1;
break;
case 2:
bgLayer = [BackgroundLayer CategoryComputer];
// variable = variable + 1;
break;
case 3:
bgLayer = [BackgroundLayer Categoryeducation];
//variable = variable + 1;
break;
case 4:
bgLayer = [BackgroundLayer CategoryElectronics];
// variable = variable + 1;
break;
case 5:
bgLayer = [BackgroundLayer CategoryEntertainment];
variable = variable + 1;
break;
case 6:
bgLayer = [BackgroundLayer CategoryGroceries];
// variable = variable + 1;
break;
case 7:
bgLayer = [BackgroundLayer CategoryHealthButy];
// variable = variable + 1;
break;
case 8:
bgLayer = [BackgroundLayer CategoryHome];
// variable = variable + 1;
break;
case 9:
bgLayer = [BackgroundLayer CategoryResturant];
// variable = variable + 1;
break;
case 10:
bgLayer = [BackgroundLayer CategoryToys];
// variable = 0;
break;
default:
bgLayer = [BackgroundLayer CategoryToys];
// variable = variable + 1;
break;
// bgLayer.frame = self.contentView.bounds;
bgLayer.frame = CGRectMake(-7, 0, [Util window_width], 72);
if ([Util isiPhone6])
bgLayer.frame = CGRectMake(-7, 0, [Util window_width], 84);
else if ([Util isiPhone6PlusDevice])
bgLayer.frame = CGRectMake(-7, 0, [Util window_width], 93);
[self.CatImageView.layer insertSublayer:bgLayer atIndex:variable];
variable = variable + 1;
【问题讨论】：
您当前的代码到底有什么问题？ 他正在分享他的知识，也许.. 嗯.. 但这是一个很好的.. :) 只能实现一种渐变色，不能实现多重，但我想使用多重渐变色，如上图所示[BackgroundLayer CategoryHealthButy] 缺少代码是您的问题吗？
没有缺码
【参考方案1】：
我可以用下面的代码实现这一点
TableViewCell.h
@interface TableViewCell : UITableViewCell
UIImageView *imageView;
UIView *viewGradient;
CAGradientLayer *gradientLayer;
- (void)setImage:(UIImage *)image andColor:(UIColor *)color;
@end
TableViewCell.m
- (void)awakeFromNib
[self.contentView setFrame:CGRectMake(0, 0, 320, 44)];
imageView = [[UIImageView alloc] initWithFrame:self.contentView.bounds];
[imageView setAutoresizingMask:UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth ];
[self.contentView addSubview:imageView];
viewGradient = [[UIView alloc] initWithFrame:self.contentView.bounds];
[viewGradient setAutoresizingMask:UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth ];
[self.contentView addSubview:viewGradient];
gradientLayer = [CAGradientLayer layer];
gradientLayer.frame = viewGradient.bounds;
[gradientLayer setStartPoint:CGPointMake(0.0, 0.5)];
[gradientLayer setEndPoint:CGPointMake(1.0, 0.5)];
[viewGradient.layer insertSublayer:gradientLayer atIndex:0];
- (void)setImage:(UIImage *)image andColor:(UIColor *)color
[imageView setImage:image];
gradientLayer.colors = [NSArray arrayWithObjects:(id)[[UIColor clearColor] CGColor], (id)[color CGColor], nil];
ViewController.m
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
TableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cell"];
switch (indexPath.row)
case 0:
[cell setImage:[UIImage imageNamed:@"Grass"] andColor:[UIColor whiteColor]];
break;
case 1:
[cell setImage:[UIImage imageNamed:@"House"] andColor:[UIColor greenColor]];
break;
case 2:
[cell setImage:[UIImage imageNamed:@"Sky"] andColor:[UIColor redColor]];
break;
default:
break;
return cell;

【讨论】：
我想要每个单元格中的多个渐变渐变，如上图所示 每个单元格中使用的颜色是否特定？ 不，我只需要使用多个渐变就可以了 你认为每个单元格有不同的梯度很难吗？ 我不认为它是否难，但我无法达到我提到的问题。你能做到吗？以上是关于CSS 如何实现一行表格的横向颜色渐变的主要内容，如果未能解决你的问题，请参考以下文章
