* feat: add Table component and related functionality
This commit adds the Table component and related functionality to the codebase. The Table component is used to display tabular data and includes features such as pagination, row deletion, row duplication, and adding new rows. The TableOptions component is also added to provide options for resetting the grid and adding new rows. Additionally, the necessary types and interfaces are updated to support the Table component. This feature enhances the user experience by allowing them to interact with tabular data in a more intuitive way.
* feat: add Edit Data trigger to TableNodeComponent
* [autofix.ci] apply automated fixes
* feat: add TableSchema class for defining table structure
* feat: add TableMixin class for table-related functionality
* feat: add TableInput class for table-related functionality
* feat: add TableInput to io module
* feat: update Column model in table schema
This commit updates the `Column` model in the table schema to include the `display_name` and `name` fields instead of `header` and `field`. It also adds validation for the `formatter` field to accept either a `FormatterType` enum value or a string. This change improves the clarity and flexibility of the table schema.
* feat: add displayEmptyAlert prop to TableComponent
This commit adds the `displayEmptyAlert` prop to the `TableComponent` in order to control whether an alert is displayed when the table has no data. By default, the alert will be shown, but it can be disabled by setting `displayEmptyAlert` to `false`. This feature enhances the flexibility of the table component by allowing users to customize the behavior when there are no rows in the table.
* This commit improves the TableAutoCellRender component by adding support for a custom formatter. The formatter can be specified as a prop and allows for rendering the cell value in different formats, such as JSON. This enhancement enhances the flexibility and customization options of the TableAutoCellRender component.
* feat: add FormatColumns function to utils.ts
This commit adds the `FormatColumns` function to `utils.ts` file. The function takes an array of `ColumnField` objects and returns an array of `ColDef` objects. It maps each `ColumnField` to a `ColDef` with properties like `headerName`, `field`, `sortable`, and `filter`. If a `ColumnField` has a `formatter` property, it sets the `cellDataType` or `cellRendererParams` accordingly. This function enhances the flexibility and customization options for formatting columns in the table.
* feat: enhance TableNodeComponent with FormatColumns function
This commit enhances the TableNodeComponent by utilizing the FormatColumns function from utils.ts. The FormatColumns function takes an array of ColumnField objects and returns an array of ColDef objects, allowing for flexible and customizable column formatting in the table. By integrating this function, the TableNodeComponent now has improved column handling capabilities.
* chore: Update TableNodeComponent and TableComponent
This commit updates the TableNodeComponent and TableComponent to improve column handling and customization options. The TableNodeComponent now utilizes the FormatColumns function from utils.ts, allowing for flexible and customizable column formatting in the table. The TableComponent now has a new prop, displayEmptyAlert, which controls whether an alert is displayed when the table has no data. These enhancements enhance the flexibility and customization options of the table components.

These enhancements enhance the flexibility and customization options of the table components.
* feat: initialize table field values as DataFrame
* feat: Enhance TableNodeComponent with duplicateRow function
This commit enhances the TableNodeComponent by adding the duplicateRow function. This function allows users to duplicate selected rows in the table. When called, it clones the selected nodes and adds the duplicated rows to the table. This feature enhances the flexibility and customization options of the TableNodeComponent.
* [autofix.ci] apply automated fixes
* feat: Remove "text" from basic_types in FormatColumns function
This commit removes the "text" value from the basic_types set in the FormatColumns function in utils.ts. The basic_types set is used to determine the column type for formatting in the table. By removing "text", we ensure that only "date" and "number" types are considered as basic types. This change improves the accuracy and consistency of column formatting in the table.

* chore: Remove unnecessary imports and initialize empty columns array in TableNodeComponent
* feat: Add default values for sortable and filterable in Column model
The code changes in `table.py` modify the `Column` model in the `langflow.schema` module. The `sortable` and `filterable` attributes of the `Column` model now have default values of `True`. This change ensures that new instances of the `Column` model will have these attributes set to `True` by default.
Based on the recent user commits and repository commits, the commit message follows the established convention of using a prefix to indicate the type of change (`feat` for a new feature) and provides a clear and concise description of the changes made.
* feat(utils.ts): add check for empty columns array in FormatColumns function to prevent errors
* feat: Add validation for TableInput value in inputs.py
The code changes in `inputs.py` add a validation function for the `value` attribute of the `TableInput` class. The function checks if the value is a list of dictionaries and raises a `ValueError` if it is not. This ensures that the `TableInput` instances have a valid value that is a list of dictionaries.

Instead of using a list comprehension to extract the error messages, the code now uses a nested list comprehension to split the error messages and extract the relevant information. This change ensures that the error message is properly formatted and provides more informative details about the validation errors.
