display为table的应用

display:table 和 display:table-cell 属性指让标签元素以表格和表格单元格的形式呈现,类似于table和td标签。目前IE8+以及其他现代浏览器都是支持此属性的, 但是IE6/7就不行了,需要写对应的hack来解决兼容性的问题 display:table和table标签的比较 display属性 table标签 display:table table table-row tr table-cell td table-header-group thead table-footer-group tfoot table-row-group tbody table-column col table-caption caption 前言 我们都知道,单元格有一些比较特别的属性,例如元素的 垂直居中对齐 , 关联伸缩 等,所以 display:table-cell 还是有不少潜在的使用价值的,虽说IE6/7不支持此属性,但是幸运的是,IE6/7一些乱糟糟的属性与渲染,我们可以其他方法实现同样或是类似的效果。 与其他一些display属性类似,table-cell同样会被其他一些CSS属性破坏,例如 float, position:absolute ,所以,在使用display:table-cell与 float:left 或是 position:absolute

How to make a JavaFX TableView cell editable without first pressing Enter?

偶尔善良 提交于 2019-11-30 21:40:47
I am learning JavaFX and implementing a TableView class. I'd like to make a cell editable without first pressing Enter or double clicking on it. I wonder if it's possible to start entering a new value without first hitting Enter? Thank you. Vladimir Minikh Looks like I've found a solution to the problem of missing first entered symbols. Data can be entered into a cell as soon as the cell is in focus. There is no necessity to press Enter first or double click on a cell before data input. Class CellField //Text box cell public class CellField { private static StringBuffer text = new StringBuffer

引言 本篇介绍Jupyter Notebook的概念以及常用快捷方式。 概述 Jupyter Notebook也称为 Ipython notebook是一种Web应用程序,您可以在其中创建和共享包含实时 代码 , 方程式 , 可视化效果 以及 文本 的文档,Jupyter Notebook是帮助您获得所需的数据科学技能的理想工具之一。 特色在于cell: cell的先后顺序不区分,区分cell执行顺序: 理解上:这一个ipy文件在内存中对应的一块缓存,当cell执行后,其它cell都可以访问。 推荐阅读 关于Jupyter Notebook的28个技巧 快捷键——更具生产力! 两种模式 键盘输入模式 Jupyter Notebooks 提供了两种不同的键盘输入模式——命令和编辑: 命令模式是将键盘和笔记本层面的命令绑定起来,并且由带有蓝色左边距的灰色单元边框表示。 编辑模式让你可以在活动单元中输入文本(或代码),用绿色单元边框表示。 1 使用 Esc 和 Enter 在命令模式和编辑模式之间跳跃。 cell的两种模式 code模式 与 markdown 模式 命令行模式(按 Esc 生效)编辑快捷键 运行选中的cell: 1 Ctrl+Enter 运行代码块并选择下面的代码块 1 Shift+Enter 运行cell并在下面添加一个新单元: 1 Alt + Enter 插入cell

How to implement MATLAB-like cell mode in Vim

筅森魡賤 提交于 2019-11-30 19:49:52
问题 In MATLAB, we can write to the editor the following %% -- a example cell -- plot(rand(3)); %% -- another cell A=rand(2^10); t=linspace(-pi,pi,2^10); compass(fft(A*sin(t)) and we can just hit Ctrl + Enter to run the cell being clicked by the mouse pointer. Now I know in Vim, I can do :'<,>'w !matlab to run a visually selected block of code. But how do I implement the MATLAB-like cell mode in Vim/gVim? For example some python code import os import subprocess import random ## 1st cell ps =[

I have a function with the following prototype function [bandwidth,density,X,Y,x,y]=kde2d(data,n,MIN_XY,MAX_XY) basically the function returns 6 outputs as above, some are in vector form while others are a numerical quantity. How can I elegantly pass the output from the function into a 1 by 6 cell array? how about [a{1:6}] = kde2d( data, n, MIN_XY, MAX_XY ); 来源: https://stackoverflow.com/questions/15523851/how-to-pass-multiple-output-from-function-into-cell-array

Rotate paragraphs or cells some arbitrary number of degrees — Itext

I have a web site where the users upload photos and create photobooks. Also, they can add text at absolute positions, rotations, and alignments. The text can have new lines. I've been using the Itext Library to automatize the creation of the Photobooks High Quality Pdfs that are printed latter on. Adding the user uploaded images to the PDFs was really simple, the problem comes when I try to add the text. In theory what I would need to do, is to define a paragraph of some defined width and height, set the users text, font, font style, alignment (center, left, right, justify), and finally set

What does the “s” attribute signify in a cell tag in XLSX

拟墨画扇 提交于 2019-11-30 18:16:30
In the XML of a worksheet in an XLSX file (Excel 2007) cell tags that have a "t" attribute equal to "s" are string types. The value tag inside the c needs to be looked up and converted via the sharedStrings document. But, some cells have s="237" and no t attribute at all. The value tag has an integer like 39448 which does not relate to the sharedStrings document. The value as it appears in Excel is a date 1/1/2008. What does the s attribute signify in a c tag in XLSX? Unknown value <c r="B47" s="237"> <v>39448</v> </c> Shared String value <c r="C47" t="s"> <v>7</v> </c> The s attribute refers
