Preparatory work: Create or edit a new post using Atto. Create a table, ideally populating each cell with example content (e.g. 'caption' as the table cell, and then each cell after that being a, b, c etc.). Add some text before and after the table. Test: Position the caret in the caption cell and click the table button. Verify that the table editing menu, rather than the table creation dialog, appears. Verify that the selection has moved to the first cell in the table. Position the caret in a th cell and click the table button. Verify that the table editing menu, rather than the table creation dialog, appears. Position the caret in a td cell and click the table button. Verify that the table editing menu, rather than the table creation dialog, appears. Select three cells in a row and click the table button. Verify that the table editing menu, rather than the table creation dialog, appears. Verify that the menu is targeting the first table cell in your selection. Select the entire table and click the table button. Verify that the table editing menu, rather than the table creation dialog, appears. Verify that the menu is targeting the first cell in the table. Select text before the table, ending with a cell in the table that is not the first cell and click the table button. Verify that the table editing menu, rather than the table creation dialog, appears. Verify that the menu is targeting the first cell (in terms of precedence) in your selection. Select text after the table, ending with a cell in the table that is not the first cell and click the table button. Verify that the table editing menu, rather than the table creation dialog, appears. Verify that the menu is targeting the first cell (in terms of precedence) in your selection. Place the caret outside the table and click the table button. Verify that the table creation dialog appears.
