Table Editing

The Editor exposes the capability of editing a data table as any other (X)HTML. The options that the table editing provides are:

• Inserting a Table
• Editing a table
• Available Table, Cell, and Accessibility tab options

As of the R3 2023 Release, the Table Wizard transmutes into two separate Table and Cell properties popup elements.

To enable the table editing, add the TableEditing tool to the configuration of the component:

    @(Html.Kendo().Editor()
      .Name("editor")
      .HtmlAttributes(new { style = "height:440px", aria_label = "editor" })
      .Tools(tools => tools.TableEditing())
    )

    <kendo-editor name="editor" style="height:440px" aria-label="editor">
      <tools>
        <tool name="tableProperties">
        </tool>
        <tool name="tableCellProperties">
        </tool>
        <tool name="createTable">
        </tool>
        <tool name="addColumnLeft">
        </tool>
        <tool name="addColumnRight">
        </tool>
        <tool name="addRowAbove">
        </tool>
        <tool name="addRowBelow">
        </tool>
        <tool name="deleteColumn">
        </tool>
        <tool name="deleteRow">
        </tool>
        <tool name="mergeCellsHorizontally">
        </tool>
        <tool name="mergeCellsVertically">
        </tool>
        <tool name="splitCellHorizontally">
        </tool>
        <tool name="splitCellVertically">
        </tool>
        <tool name="tableAlignLeft">
        </tool>
        <tool name="tableAlignCenter">
        </tool>
        <tool name="tableAlignRight">
        </tool>
      </tools>
    </kendo-editor>

Inserting a Table

To insert a new table by using the Table Wizard dialog:

1. Click the Create Table tool.
2. To open the dialog, click the Table Wizard button.
3. Configure the table you want to insert.
4. Click the OK button.

To quickly create a plain table, click the Create Table tool and choose the row and column dimensions.

Editing a Table

To modify an existing table or a table cell:

1. Select the table or the table cell to edit.
2. Click the Table Wizard tool in the toolbar.

You can resize the table rows and columns by dragging the cell border with the mouse and without using the Table Wizard dialog.

The table and cell options that are available in the Table Wizard are displayed in the following three tabs:

• Table—The available options for the table element.
• Cell—The available options for the selected cell or all cells in the table.
• Accessibility—The available options related to accessibility.

Available Options

The Editor provides a set of editing options through its Table, Cell, and Accessibility tabs.

Table Tab

The Table tab provides the following options:

• Width—Changes the width of the table (in pixels, em, or percent).
• Height—Changes the height of the table (in pixels, em, or percent).
• Columns—Defines the columns of the table.
• Rows—Defines the rows of the table.
• Cell Spacing—Specifies the space between the cells (cellspacing attribute).
• Cell Padding—Specifies the padding in the cells (cellpadding attribute).
• Alignment—Specifies the text alignment in the cells.
• Background—Specifies the background color of the table.
• CSS Class—Defines the class names for the table element (white space-separated).
• ID—Defines the id of the table element.
• Border—Defines the border size (in pixels only) and color.
• Border Style—Defines the border style (none, hidden, dotted, dashed, solid, double, groove, ridge, inset, outset, initial, and inherit).
• Collapse borders—Adds an inline style to that table element with the border-collapse: collapse rule (border-collapse property).

Cell Tab

The Cell tab provides the following options:

• Apply to all cells—Applies the changes to all cells in the table.
• Width—Changes the width of the cell or cells (in pixels, em, or percent).
• Height—Changes the height of the cell or cells (in pixels, em, or percent).
• Cell Margin—Defines the margin of the cell or cells.
• Cell Padding—Defines the padding of the cell or cells.
• Alignment—Specifies the text alignment of the cell or cells.
• Background—Specifies the background color of the cell or cells.
• CSS Class—Defines class names for the cells (white space-separated).
• ID—Defines the id of the cells.
• Border—Defines the border size (in pixels only) and color of the cells.
• Border Style—Defines the border style (none, hidden, dotted, dashed, solid, double, groove, ridge, inset, outset, initial, and inherit).
• Wrap text—When unchecked, applies a white-space: nowrap style to the cells (white-space property).

Accessibility Tab

As of the R3 2023 Release, the accessibility tab becomes a section in the Advanced tab in the new Table Properties popup.

The Accessibility tab provides the following options:

• Header Rows—Allows the user to specify the number of rows in the table that should belong to header and should render <th> cell elements instead of <td>. When creating a new Table, those rows will be placed within a <thead> element.
• Header Cols—Allows the user to specify the number of columns in the table that would be headers for their respective rows. The cells will be rendered as <th> elements instead of <td>.
• Caption—Adds a caption element for the table with the respective text.
• Alignment—Defines the text alignment of the caption.
• Summary—Adds a summary attribute to the table using value defined. The summary attribute has been deprecated in HTML5 and its use should be avoided when possible.
• Associate headers—Allows the user to specify the mode in which content cells should be associated with their header cells. it provides the following three options:
  • None - Will not explicitly associate cells. That is the default option and it is appropriate for tables with simple structure (no merged cells).
  • Associate using 'scope' attribute - The wizard will add the appropriate scope attribute to all header cells.
  • Associate using Ids - The wizard will assign IDs to all header cells and will inject headers attribute with the appropriate value to all data (and header, if needed) cells.
