问题 I have a tableView with several cells (created by MVVM-architecture). In ViewController I fill my tableView like this: tbv.registerCells( withModels: FirstViewModel.self, SecondViewModel.self, ThirdViewModel.self) My task is to put my TableView in one cell of CollectionView. I thought l have to create CollectionView in my ViewController, after it create CollectionViewCell and CollectionCellViewModel, but how to do it exactly I don't understand. If you know, how to make it, help. 回答1: How I

问题 I used Hough lines to get intersection of horizontal and vertical lines in this image: but the complexity grows with the grid cells count significantly. Is there any simple way to complete the grid without using line detection ? Thank you. 回答1: Here's a potential solution using morphological operations with OpenCV Obtain binary image. Load image, grayscale, Gaussian blur, Otsu's threshold Obtain horizontal/vertical lines masks. Create horizontal/vertical kernel and isolate horizontal/vertical

问题 I'm using NPOI to create fixed worksheet template in Sheet1, and need data from Sheet2 that's in date format.I generate DataTable from database to set data in Sheet2. It's my code : private DataTable getWeek() { strConn = WebConfigurationManager.ConnectionStrings["myConn"].ConnectionString; conn = new OdbcConnection(strConn); conn.Open(); sql = "SELECT week, sunday, saturday FROM tb_weekreferences"; da = new OdbcDataAdapter(sql, conn); dt = new DataTable(); da.Fill(dt); conn.Close(); return

问题 I would like to know how do i change the background color of a cell in a Table without any response from users. For example, if there is a change in one of my variables due to some unrelated method calls, which I would like for to be reflected in my table. Example, a method changes a value of my array that I used to initialize my table, however the user had no hand in it, like say a elapsed time change in value. So how do I reflect it on my table, or is there any way I could manually call the

问题 I have read through many forums and tried the solution there but none of them have worked I still have a small gap between all my images. Here is the code: <table id="Table"> <tr> <td id="td1"><h2>~ Curling ~</h2></td> <td id="td2" rowspan="2"><img src="../images/curlingMid.jpg" width="100%" height="100%" border="2" alt=""/></td> <td id="td1"><h2>~ Curling ~</h2></td> </tr> </table> #td1 { width: 32%;vertical-align: text-top; } #td2 { padding-right: 5px; padding-top: 5px; } 回答1: The image is

问题 I am trying to set data type of cell, but it seems that's impossible to do with EPPlus. If I place a number as value in cell, I get General data type in exported Excel file. If set NumberFormat of Cells, for example: workSheet.Cells[range].Style.Numberformat.Format = "mm/dd/yyyy hh:mm:ss"; Then I still will not get Date or Time. Exported Excel file will show cells as Custom data type. I can get General or Custom data types only. I want to set Cells' data type to Time, but I can't. The problem
