问题 I would really like some help with one of my projects. I am a graphic design student and have little to no programming experience.

A friend of mine suggested word wrapping but I can't find anything online to help me

阅读更多关于 Java code for wrapping text lines to a max line width

问题 Before I re-invent the wheel (poorly), I'd like to know if there is a some existing Java code for wrapping text lines to a given maximum width.

"maximum width" refers to the number of characters on a line. 回答1: Apache commons has WordUtils and wrap

Calculating size of text before drawing to a canvas

阅读更多关于 Calculating size of text before drawing to a canvas

问题 I'm using Delphi 7. I'm more than familiar with using a canvas and drawing text to a canvas, and also using TCanvas.TextHeight etc. The problem arises when I want to implement Word Wrap. Not only do I need the best way to draw text to a canvas and have it automatically wrap to a given width constraint, but I also need to know how high (or how many lines) it will be after it's wrapped. I need to prepare another image before I draw the text, an image which needs to be just big enough to place

表格中的table-layout属性讲解

阅读更多关于表格中的table-layout属性讲解

定义和用法 tableLayout 属性用来显示表格单元格、行、列的算法规则。 table-layout有三个属性值：auto、fixed、inherit。 fixed：固定表格布局固定表格布局与自动表格布局相比，允许浏览器更快地对表格进行布局。在固定表格布局中，水平布局仅取决于表格宽度、列宽度、表格边框宽度、单元格间距，而与单元格的内容无关。通过使用固定表格布局，用户代理在接收到第一行后就可以显示表格。如果指定了单元格的宽度，则会按指定的宽度限定每个单元格宽度，跟内容无关（如果指定的是比例，会永远保持这个比例），这样就可能出现内容飘到单元格之外的情况。如果没有指定单元格的宽度，则会根据table的总宽度平分到每个单元格。 auto：自动表格布局在自动表格布局中，列的宽度是由列单元格中没有折行的最宽的内容设定的。此算法有时会较慢，这是由于它需要在确定最终的布局之前访问表格中所有的内容。自动表格布局时，设置单元格的宽度是没有效的。说明该属性指定了完成表布局时所用的布局算法。固定布局算法比较快，但是不太灵活，而自动算法比较慢，不过更能反映传统的 HTML 表。 table表格中的内容如果是中文，一般情况下都会自动换行。但如果内容是英文或数字，内容过长时文字会飘到单元格之外，也就是内容不会自动换行，这时候需要配合属性 word-wrap:break-word
