TableCellPosition Struct

Defines a cell position in a table.

Namespace : DevExpress.Blazor.RichEdit

Assembly : DevExpress.Blazor.RichEdit.v25.2.dll

NuGet Package : DevExpress.Blazor.RichEdit

Declaration

csharp

public readonly struct TableCellPosition

Remarks

A TableCellPosition object stores a cell’s position in a table. Pass two cell positions to the MergeCellsAsync method to merge all cells in the specified range. The result cell has the same appearance settings as the first cell in the range.

Note

The MergeCellsAsync method throws an exception if the table does not contain a cell at the specified position.

The following example merges 6 cells:

razor

<DxRichEdit @ref="richEdit" />

@code {
    DxRichEdit richEdit;
    protected override async Task OnAfterRenderAsync(bool firstRender) {
        if (firstRender)
            try {
                await InitializeDocument();
            }
            catch (TaskCanceledException) { }
        await base.OnAfterRenderAsync(firstRender);
    }

    async Task InitializeDocument() {
    /* Surround the code that contains an asynchronous operation with a try-catch block to handle
    the OperationCanceledException. This exception is thrown when an asynchronous operation is canceled. */
        try {
            var columnCount = 4;
            var rowCount = 5;
            richEdit.DocumentAPI.BeginUpdate();
            Table firstTable = await richEdit.DocumentAPI.Tables.CreateAsync(0, columnCount, rowCount);
            var startPosition = new TableCellPosition(0, 0); // The first cell in the first row
            var endPosition = new TableCellPosition(2, 1); // The second cell in the third row
            await firstTable.MergeCellsAsync(startPosition, endPosition);
        }
        catch (OperationCanceledException e) {
            Console.WriteLine($"{nameof(OperationCanceledException)} thrown with message: {e.Message}");
        }
    }
}

Call the SplitAsync method to split a cell into multiple smaller cells.
