问题 This question has previously been posted, like Alphabetical sections in table table view in swift, but I can't really wrap my head around it when I try to implement it into my own code. I have the standard functions to get the alphabetic sections in place: func numberOfSections(in tableView: UITableView) -> Int { return collation.sectionTitles.count } func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? { return collation.sectionTitles[section] } func

问题 I added cool css menu from one website, it uses jquery version 2. and above, but I had my own custom elements which now works not properly with that version, IE always drops error on that jquery, I wonder if I could disable jquery in some sections of page, for example <div>jquery version 2.* enabled here</div> <div>jquery is disabled here</div> so that I can use my own custom elements without touching jquery functions. 回答1: No you can not.

问题 I have a tableview setup whereby every row has its own custom section header. This is done with a prototype cell in the story board. I have a segue to a view controller on the click event of a row. I achieved this by ctrl dragging on the storyboard. I want my section header to segue to a different controller, however. I ctrl dragged from my header prototype cell to a view controller on the storyboard also. The result is that both clicking on the row and clicking on the header of the row are

问题 I want to divide my Rmarkdown document like in picture. One column for the first section then two columns in the other sections. used \onecolumn and \twocolumn but each section is created in a single page. Is there a solution to fix it? 回答1: This article has been published in a journal of the AMS. Fortunately, the rticle package supports the AMS journals.

问题 I have this program part, which puts specific numbers in all sections. What I would like to have is to make the iterator keep counting the words, even if the word are same. This recent code sets the same number when same word comes again.

问题 I have been using HTML for ages, but had never looked too deep into the new HTML5 elements and HTML structuring/sectioning. I have done some reading on MDN and w3s, but am still quite confused. Below is an image of the layout, the document structure of the body section, and some question that I have. <body> <header id='header'> <h1 id='header-left'> <img id='logo' /> </h1> <div id='header-right'> <nav id='nav-links-cont'> <a class='nav-links' href='' alt=''>FILTER</a> <a class='nav-links'

问题 I've got an issue and I'm wondering if it's possible to solve. I have a UITableView that uses Core Data and NSFetchedResultsController. A big part of my app is organizing things based on dates. Ideally, I'd like to divide the TableView into sections based off of 3 date ranges. These ranges would be between now and 2 days, between 2 days and 6 days, and 10 days and beyond. The user has a UIDatePicker, and when they enter a date it would be automatically put into one of these organized sections
