datatable

问题 Context I would like to have a footer under my grid to show some stats about the datas. Such as Sum of some columns and average of some other. Half solutions I've found I've found two things intersting to help me do this, binding the databox to a bindingSource, BUT it's only the selected line that is shown into the textBox... myTextBox.DataBindings.add("Text", myGrid.DataSource,"Weight") And getting the Sum of a column in the grid, BUT it doesn't update if I change the grid :S myTextBox.Text

问题 I have encountered a great issue while using Laravel's datatables. I have a model that has 3 values automatically encrypted (using Crypt) by setter/getter. I am using datatables to render a table by doing so: return datatables()->of(Patient::query()) ->addColumn('name_surname', function($row){ return $row->name.' '.$row->surname; }) ->make(true); There is 3 ways to pass a model to datatable: by query (Patient::query()) by collection (Patient::all()) by DB facade The third doesnt decrypt data.

问题 So I have created this variable that is called mc_split_device inside the datatable called mc_with_devices . However, If I type mc_with_devices$mc_split I get the values of the column mc_split_device while I never created any variable with the name mc_split . 回答1: See Hadley Wickham's Advanced R: $ is a shorthand operator, where x$y is equivalent to x[["y", exact = FALSE]]. It’s often used to access variables in a data frame, as in mtcars$cyl or diamonds$carat. So the exact=FALSE is the

问题 I simply want to compare the first col of the datatable called "name" to items in the array. They can be multiple rows in the datatable with the same name. After it has compared all items in the array it should delete the rows that were NOT from the datatable. The output result can be the datatable itself or list array (prefer this) however this should retain all the columns from datatable. Possibly want to use linq query. code: DataTable dt = new DataTable("TestTable"); dt.Columns.Add(new

问题 I'm trying to delete a selected row from a DataTable by retrieving the value of the first cell (id) and passing it to the deleteRow function. How do I get this value? child: DataTable( columns: data.first.keys .map((dynamic keys) => DataColumn(label: Text(keys.toString()))) .toList(), rows: data.map((map) { return DataRow( onSelectChanged: (bool selected) { if (selected) { try { //determine the id of the selected row int selectedId = /*get index of selected row and return value of the first

问题 I have a datatable in R Shiny, and one of the columns, Keywords, contains multiple entries for some rows, separated by a comma. I would like these multiple entries to be individually searchable. The default search feature for datatable treats these entries as one, long, single item. For example, row 2's value for the column Keywords is "Keyword1, Keyword2". I would like the user to be able to search for either "Keyword1" OR "Keyword2" and find row 2. Currently, the default search bar in
