Because of it, we need to fill all\n * empty elements which should be selectable with elements or characters called \"fillers\". Unfortunately there is no one\n * universal filler, this is why two types are uses:\n *\n * * Block filler is an element which fill block elements, like `

`. CKEditor uses `
` as a block filler during the editing,\n * as browsers do natively. So instead of an empty `

` there will be `


`. The advantage of block filler is that\n * it is transparent for the selection, so when the caret is before the `
` and user presses right arrow he will be\n * moved to the next paragraph, not after the `
`. The disadvantage is that it breaks a block, so it cannot be used\n * in the middle of a line of text. The {@link module:engine/view/filler~BR_FILLER `
` filler} can be replaced with any other\n * character in the data output, for instance {@link module:engine/view/filler~NBSP_FILLER non-breaking space} or\n * {@link module:engine/view/filler~MARKED_NBSP_FILLER marked non-breaking space}.\n *\n * * Inline filler is a filler which does not break a line of text, so it can be used inside the text, for instance in the empty\n * `` surrendered by text: `foobar`, if we want to put the caret there. CKEditor uses a sequence of the zero-width\n * spaces as an {@link module:engine/view/filler~INLINE_FILLER inline filler} having the predetermined\n * {@link module:engine/view/filler~INLINE_FILLER_LENGTH length}. A sequence is used, instead of a single character to\n * avoid treating random zero-width spaces as the inline filler. Disadvantage of the inline filler is that it is not\n * transparent for the selection. The arrow key moves the caret between zero-width spaces characters, so the additional\n * code is needed to handle the caret.\n *\n * Both inline and block fillers are handled by the {@link module:engine/view/renderer~ViewRenderer renderer} and are not present in the\n * view.\n *\n * @module engine/view/filler\n */\n/**\n * Non-breaking space filler creator.

It will clip table cells that extend beyond their section.\n * 2. It will add empty table cells to the rows that are narrower than the widest table row.\n *\n * ## Clipping overlapping table cells\n *\n * Such situation may occur when pasting a table (or a part of a table) to the editor from external sources.\n *\n * For example, see the following table which has a cell (FOO) with the rowspan attribute (2):\n *\n * ```xml\n *
\n * \n * FOO\n * BAR\n * \n * \n * BAZ\n * XYZ\n * \n *

FOOBAR
BAZXYZ
\n * ```\n *\n * In the above example the table will be rendered as a table with two rows: one in the header and second one in the body.\n * The table cell (FOO) cannot span over multiple rows as it would extend from the header to the body section.\n * The `rowspan` attribute must be changed to (1). The value (1) is the default value of the `rowspan` attribute\n * so the `rowspan` attribute will be removed from the model.\n *\n * The table cell with BAZ in the content will be in the first column of the table.\n *\n * ## Adding missing table cells\n *\n * The table post-fixer will insert empty table cells to equalize table row sizes (the number of columns).\n * The size of a table row is calculated by counting column spans of table cells, both horizontal (from the same row) and\n * vertical (from the rows above).\n *\n * In the above example, the table row in the body section of the table is narrower then the row from the header: it has two cells\n * with the default colspan (1). The header row has one cell with colspan (1) and the second with colspan (2).\n * The table cell (FOO) does not extend beyond the head section (and as such will be fixed in the first step of this post-fixer).\n * The post-fixer will add a missing table cell to the row in the body section of the table.\n *\n * The table from the above example will be fixed and rendered to the view as below:\n *\n * ```xml\n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n *

\n * ```\n *\n * ## Collaboration and undo - Expectations vs post-fixer results\n *\n * The table post-fixer only ensures proper structure without a deeper analysis of the nature of the change. As such, it might lead\n * to a structure which was not intended by the user. In particular, it will also fix undo steps (in conjunction with collaboration)\n * in which the editor content might not return to the original state.\n *\n * This will usually happen when one or more users change the size of the table.\n *\n * As an example see the table below:\n *\n * ```xml\n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n *
1112
2122
\n * ```\n *\n * and the user actions:\n *\n * 1. Both users have a table with two rows and two columns.\n * 2. User A adds a column at the end of the table. This will insert empty table cells to two rows.\n * 3. User B adds a row at the end of the table. This will insert a row with two empty table cells.\n * 4. Both users will have a table as below:\n *\n * ```xml\n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n *
1112(empty, inserted by A)
2122(empty, inserted by A)
(empty, inserted by B)(empty, inserted by B)
\n * ```\n *\n * The last row is shorter then others so the table post-fixer will add an empty row to the last row:\n *\n * ```xml\n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n *
1112(empty, inserted by A)
2122(empty, inserted by A)
(empty, inserted by B)(empty, inserted by B)(empty, inserted by the post-fixer)
\n * ```\n *\n * Unfortunately undo does not know the nature of the changes and depending on which user applies the post-fixer changes, undoing them\n * might lead to a broken table. If User B undoes inserting the column to the table, the undo engine will undo only the operations of\n * inserting empty cells to rows from the initial table state (row 1 and 2) but the cell in the post-fixed row will remain:\n *\n * ```xml\n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n *
1112
2122
(empty, inserted by B)(empty, inserted by B)(empty, inserted by a post-fixer)
\n * ```\n *\n * After undo, the table post-fixer will detect that two rows are shorter than others and will fix the table to:\n *\n * ```xml\n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n *
