Creating a Table

A table is a perfect format for some types of data, including statistical information. CKEditor not only lets you add and edit this common text placeholder in a quick and easy way but also offers advanced customization options.

To create a table in CKEditor, press the button on the toolbar. The Table Properties dialog window that will open lets you set configuration options that define table size, its display properties, or other advanced properties.

The Table Properties dialog window includes two tabs that group table options:

• Table Properties
• Advanced

Both tabs contain the and buttons that let you accept the changes or close the dialog window without performing any changes, respectively.

Once inserted into the document, a table can be edited at any time by double-clicking it or choosing the Table Properties option from the table context menu. The Table Properties dialog window will open again and you will be able to introduce changes to the table configuration options.

If you attempt to close the Table Properties dialog window without saving the changes, you will be prompted to do so:

You can either proceed without saving your changes by choosing OK or close the alert window with the Cancel command and save the changes.

Table Properties

The Table Properties tab is the default tab that opens after you press the button on the toolbar. It allows you to set the table dimensions and configure the way it will appear in the document.

Below is an overview of all Table Properties tab elements:

• Rows – the number of rows in the table (obligatory).
• Columns – the number of columns in the table (obligatory).

• Width – the width of the table in pixels or percent. Changing the unit to percent lets you set the proportion of the editing area that the table will occupy.
• Height – the height of the table in pixels.

• Headers – the drop-down list that formats certain table cells as headers, which applies special formatting to them. You can apply header formatting to First Row, First Column or Both.
• Border size – the thickness of the table border in pixels.
• Alignment – the alignment of text in the table. The following options are available: Left, Center, Right.

• Cell spacing – the space between individual cells as well as cells and table border, in pixels.
• Cell padding – the space between the cell border and its contents, in pixels.

• Caption – the label of the table that is displayed on top of it.
• Summary – the summary of the table contents that is available for assistive devices like screen readers. It is a good practice to provide your tables with meaningful summary text in order to make it more accessible to users with disabilities.

Advanced

The Advanced tab lets you configure additional image options such as assign it an ID, a class, a language direction, or CSS style properties. It is meant for advanced users with knowledge of HTML and CSS and gives nearly endless possibilities as far as the presentation of the table is concerned.

Below is an overview of all Advanced tab elements:

• Id – a unique identifier for a table element in the document (id attribute).
• Language Direction – the direction of the text in the table: left to right (LTR) or right to left (RTL) (dir attribute).
• Stylesheet Classes – a class of the table element (class attribute). Note that a table element might be assigned more than one class. If this is a case, separate class names with spaces.
• Style – CSS style definitions (style attribute). Note that each value must end with a semi-colon and individual properties should be separated with spaces.

Working With Tables

Once inserted into the document, the table can be modified. To edit the table, either double-click it or use the right mouse button to open the table context menu.

The context menu for a table element

To delete the whole table and its contents, use the Delete Table option.

When you choose the Table Properties option, the dialog window of the same name will appear. It allows you to change the configuration options that were set when the table was created, except the number of rows and columns which are grayed out.

Additionally the table context menu lets you modify the rows, columns or particular table cells. This method makes it possible to insert new rows, columns or cells in specified locations as well as merge and split cells.
