Columns where row[col]!Although DataTables doesn't have row grouping built-in picking one of the many methods available would overly limit the DataTables coreit is most certainly possible to give the look and feel of row grouping.

In the example below the 'group' is the office location, which is based on the information in the third column which is set to hidden. The grouping indicator is added by the drawCallback function, which will parse through the rows which are displayed, and enter a grouping TR element where a new group is found.

A click event handler is added for the grouping rows to allow the grouping order to be restored as well as ordering by any other column. Important note: DataTables now has a RowGroup extension that provides a formal API for the abilities in this demo and extends upon them in a number of significant and useful ways. This example is retained as a useful demonstration of how the drawCallback option can be used, but for new sites that make use of row grouping, it is suggested that you use the new RowGroup extension.

In addition to the above code, the following Javascript library files are loaded for use in this example:. This example uses a little bit of additional CSS beyond what is loaded from the library files belowin order to correctly display the table.

The additional CSS used is shown below:. The following CSS library files are loaded for use in this example to provide the styling of the table:. This table loads data by Ajax. The latest data that has been loaded is shown below. This data will update automatically as any additional data is loaded.

The script used to perform the server-side processing for this table is shown below. Please note that this is just an example script using PHP. Server-side processing scripts can be written in any language, using the protocol described in the DataTables documentation. DataTables designed and created by SpryMedia Ltd. Privacy policy.

The Remove method removes the row from the collection. In contrast, Delete marks the DataRow for removal. The actual removal occurs when you call AcceptChanges method. By calling Deleteyou can programmatically check which rows are marked for removal before actually deleting them.

Add params object[] values instead of four lines. You can also use DataTable. AddRange to add columns with on statement. Complete code would be.

Add "Name", "Marks". The DataRowCollection. Add method has an overload that takes a param array of objects. This method lets you pass as many values as needed, but they must be in the same order as the columns are defined in the table.

So while this is a convenient way to add row data, it can be risky to use. If the table structure changes your code will fail. Note: There is no need to Clear the DataTable after creating it.

Then we add 4 columns—these include a type, specified with typeof. Step 3: We add the actual data as rows. The 4 arguments to each Add call match up with the 4 columns already added. Step 4: We print a cell value from the first row row 0 and the Dosage column which is an int. C program that uses DataTable using System; using System.

We add 4 columns, each with a Type. Add "Dosage", typeof int ; table. Add "Drug", typeof string ; table. Add "Patient", typeof string ; table.

Add 25"Indocin", "David", DateTime. Now ; table. Add 50"Enebrel", "Sam", DateTime. Add 10"Hydralazine", "Christoff", DateTime. Add 21"Combivent", "Janet", DateTime.

Generic method: Field is a generic method.

So we must specify its parametric type here, int to indicate its behavior. Rows: Often we must access the rows of a DataTable.

The Rows property, which can be looped over, is ideal here. C program that uses Rows, Field using System; using System. Loop over all rows. Write value of first field as integer. WriteLine row. DataTable can be placed in a using statement. This can help programs' performance. Often the using block construct helps improve resource management. Tip 2: In this example, the Dispose method is invoked. After the using statement, Dispose on DataTable is called.

Dispose: When Dispose is called, native resources are released. This may help resource usage problems. C program that uses using statement using System; using System. Add "Name"typeof string ; table.Keep in touch and stay productive with Teams and Officeeven when you're working remotely.

If you have a worksheet with data in columns that you need to rotate to rearrange it in rows, use the Transpose feature. For example, if your data looks like this, with Sales Regions in the column headings and and Quarters along the left side:.

The Transpose feature will rearrange the table such that the Quarters are showing in the column headings and the Sales Regions can be seen on the left, like this:. Choose a new location in the worksheet where you want to paste the transposed table, ensuring that there is plenty of room to paste your data.

Right-click over the top-left cell of where you want to paste the transposed table, then choose Transpose. After rotating the data successfully, you can delete the original table and the data in the new table will remain intact. If your data includes formulas, Excel automatically updates them to match the new placement.

If you want to rotate your data frequently to view it from different angles, consider creating a PivotTable so that you can quickly pivot your data by dragging fields from the Rows area to the Columns area or vice versa in the PivotTable Field List. You can paste data as transposed data within your workbook. Transpose reorients the content of copied cells when pasting. Data in rows is pasted into columns and vice versa. On the Home tab, click the Paste icon, and select Paste Transpose.
