);
```

moveRow(originRowIndex: number, targetRowIndex: targetColumnIndex, options: ?MovementOptions) → fn(tr: Transaction) → Transaction\ Returns a new transaction that moves the origin row to the target index;
by default "tryToFit" is false, that means if you try to move a row to a place where we will need to split a row with merged cells it'll throw an exception, for example:
```
     ____________________________
    |      |      |             |
 0  |  A1  |  B1  |     C1      |
    |______|______|______ ______|
    |      |             |      |
 1  |  A2  |     B2      |      |
    |______|______ ______|      |
    |      |      |      |  D1  |
 2  |  A3  |  B3  |  C2  |      |
    |______|______|______|______|
```
if you try to move the row 0 to the row index 1 with tryToFit false, it'll throw an exception since you can't split the row 1; but if "tryToFit" is true, it'll move the row using the current direction.
We defined current direction using the target and origin values if the origin is greater than the target, that means the course is bottom-to-top, so the tryToFit logic will use this direction to determine if we should move the column to the right or the left.
for example, if you call the function using moveRow(0, 1, { tryToFit: true }) the result will be:
```
     ____________________________
    |      |             |      |
 0  |  A2  |     B2      |      |
    |______|______ ______|      |
    |      |      |      |  D1  |
 1  |  A3  |  B3  |  C2  |      |
    |______|______|______|______|
    |      |      |             |
 2  |  A1  |  B1  |     C1      |
    |______|______|______ ______|
```
since we could put the row zero on index one, we pushed to the best place to fit the row index 0, in this case, row index 2.

-------- HOW TO OVERRIDE DIRECTION --------

If you set "tryToFit" to "true", it will try to figure out the best direction place to fit using the origin and target index, for example:

     ____________________________
    |      |      |             |
 0  |  A1  |  B1  |     C1      |
    |______|______|______ ______|
    |      |             |      |
 1  |  A2  |     B2      |      |
    |______|______ ______|      |
    |      |      |      |  D1  |
 2  |  A3  |  B3  |  C2  |      |
    |______|______|______|______|
    |      |             |      |
 3  |  A4  |     B4      |      |
    |______|______ ______|      |
    |      |      |      |  D2  |
 4  |  A5  |  B5  |  C3  |      |
    |______|______|______|______|

If you try to move the row 0 to row index 4 with "tryToFit" enabled, by default, the code will put it on after the merged rows, but you can override it using the "direction" option.

-1: Always put the origin before the target

moveColumn(originColumnIndex: number, targetColumnIndex: targetColumnIndex, options: ?MovementOptions) → fn(tr: Transaction) → Transaction\ Returns a new transaction that moves the origin column to the target index;
by default "tryToFit" is false, that means if you try to move a column to a place where we will need to split a column with merged cells it'll throw an exception, for example:
```
   0      1         2

```

if you try to move the column 0 to the column index 1 with tryToFit false, it'll throw an exception since you can't split the column 1; but if "tryToFit" is true, it'll move the column using the current direction.

We defined current direction using the target and origin values if the origin is greater than the target, that means the course is right-to-left, so the tryToFit logic will use this direction to determine if we should move the column to the right or the left.

   0       1             2

Utils for document transformation

removeParentNodeOfType(nodeType: NodeType | [NodeType]) → fn(tr: Transaction) → Transaction\ Returns a new transaction that removes a node of a given nodeType. It will return an original transaction if parent node hasn't been found.
```
dispatch(
  removeParentNodeOfType(schema.nodes.table)(tr)
);
```

replaceParentNodeOfType(nodeType: NodeType | [NodeType], content: ProseMirrorNode | Fragment) → fn(tr: Transaction) → Transaction\ Returns a new transaction that replaces parent node of a given nodeType with the given content. It will return an original transaction if either parent node hasn't been found or replacing is not possible.
```
const node = schema.nodes.paragraph.createChecked({}, schema.text('new'));

dispatch(
 replaceParentNodeOfType(schema.nodes.table, node)(tr)
);
```

removeSelectedNode(tr: Transaction) → Transaction\ Returns a new transaction that removes selected node. It will return an original transaction if current selection is not a NodeSelection.
```
dispatch(
  removeSelectedNode(tr)
);
```

replaceSelectedNode(content: ProseMirrorNode | ProseMirrorFragment) → fn(tr: Transaction) → Transaction\ Returns a new transaction that replaces selected node with a given node, keeping NodeSelection on the new node. It will return the original transaction if either current selection is not a NodeSelection or replacing is not possible.
```
const node = schema.nodes.paragraph.createChecked({}, schema.text('new'));
dispatch(
  replaceSelectedNode(node)(tr)

```

safeInsert(content: ProseMirrorNode | Fragment, position: ?number, tryToReplace: ?boolean) → fn(tr: Transaction) → Transaction\ Returns a new transaction that inserts a given content at the current cursor position, or at a given position, if it is allowed by schema. If schema restricts such nesting, it will try to find an appropriate place for a given node in the document, looping through parent nodes up until the root document node. If tryToReplace is true and current selection is a NodeSelection, it will replace selected node with inserted content if its allowed by schema. If cursor is inside of an empty paragraph, it will try to replace that paragraph with the given content. If insertion is successful and inserted node has content, it will set cursor inside of that content. It will return an original transaction if the place for insertion hasn't been found.
```
const node = schema.nodes.extension.createChecked({});

```
dispatch(
  removeNodeBefore(state.tr)
);
```

setTextSelection(position: number, dir: ?number = 1) → fn(tr: Transaction) → Transaction\ Returns a new transaction that tries to find a valid cursor selection starting at the given position and searching back if dir is negative, and forward if positive. If a valid cursor position hasn't been found, it will return the original transaction.
```
dispatch(
  setTextSelection(5)(tr)
);
