formatting

问题 Using the following code how can I set the formatting so that CurrencyValue1 and CurrencyValue2 is shown with a dollar (as a currency value) in the chart? function drawChart() { var data = new google.visualization.DataTable(); data.addColumn('date', 'Date'); data.addColumn('number', 'CurrencyValue1'); data.addColumn('number', 'CurrencyValue2'); data.addRows(1); data.setValue(0, 0, new Date(2011, 8, 12)); data.setValue(0, 1, 300.0000); data.setValue(0, 2, 759.1707); var chart = new google

问题 This may seem to defeat the purpose of a code block, but I'd like to be able to bold something within a code block. For example, if I wanted to bold the return line: int main(void) { **return 0;** } 回答1: You would have to do this in HTML, by design. However, inside Markdown code spans and blocks, angle brackets and ampersands are always encoded automatically. <pre> int main(void) { <b>return 0;</b> } </pre> 来源： https://stackoverflow.com/questions/10063896/how-do-i-add-markdown-formatting-in-a

问题 So if I have a HTML heading like this <h2>A Heading</h2> and I run Edit -> Format Document it ends up looking like this <h2> A Heading</h2> why is this? It doesn't do it to other block elements, but it does do it to other inline elements (eg <label> ). Update : To clarify, I mean why is this the default, not where are the settings to change this 回答1: It does it because those are its default settings. In older browsers, sometimes having the end tag of a block or inline element on a new line

问题 Mathematica can be used to write very nice documents. Does anyone know if it is possible to write documents with 2 columns? If so, can you provide some examples or links to other notebooks that show this style. 回答1: I don't think any good implementation of multicolumns are supported in Mathematica - it's not really compatible with the structure of the notebook interface. The fact that publicon does not support proper multiple columns is probably a good hint that Mathematica does not. Q: Does

问题 I been working on parsing out bookmarks from an export file generated by google bookmarks. This file contains the following date attributes: ADD_DATE="1231721701079000" ADD_DATE="1227217588219000" These are not standard unix style timestamps. Can someone point me in the right direction here? I'll be parsing them using c# if you are feeling like really helping me out. 回答1: 1231721701079000 looks suspiciously like time since Jan 1st, 1970 in microseconds. perl -wle 'print scalar gmtime

问题 I've been looking at return values for Type.Namespace , Type.Name , Type.FullName , and Type.AssemblyQualifiedName . There are inconsistencies. For an inner class like ConsoleApplication8.Program+InnerClass , Namespace returns ConsoleApplication8 and Name returns InnerClass , omitting Program , so concatenating Type.NameSpace and Type.Name would be an incomplete representation of the class name (just as an example). Even the FullName property is inconsistent. Although it omits assembly name

问题 I tracked down a bug in my application that occurred for people in countries where the default decimal symbol was a comma instead of a period. Is there any way in C# to set the decimal symbol for my application without affecting other apps or permanently changing the system settings? I tried this but it says the NumberDecimalSeparator is readonly. Thread.CurrentThread.CurrentCulture.NumberFormat.NumberDecimalSeparator = "."; 回答1: I you still need to do that you can change the CurrentCulture

问题 I have a list of data in text format that looks as follows Name1 Name2 location job date amount Name1 Name2 location job date amount Name1 Name2 location job date amount I need to somehow make this into Name1 Name2 location job date amount ... I figure there has got to be a way to grab every other newline with either regex or excel. I could write a python script but this file has been a pain and was hoping there would be an easier way to do it. EDIT: adding what I've tried below: Sorry, I
