To hide a column in a table, you can use the CSS attribute "display" and set it to "none". This attribute is used in the example of hiding the "Name" column in the table where the CSS code is applied to the table element.
The display property can also be used to show a column again by setting it to "table-column". This is demonstrated in the example where the CSS code is used to show the "Name" column again.
By using the display property, you can easily customize which columns are visible or hidden in a table, making it a convenient solution for dynamic table layouts.

Hiding Columns
Hiding columns in a table can be done dynamically using state or the setColumnVisibility table instance API, which was introduced in v2.3.0.
You can control how columns are hidden dynamically using state instead of initialState along with the onColumnVisibilityChange table option.
By default, column hiding is only enabled on data columns, but you can turn it back on for display columns by setting the enableHiding option to true in the displayColumnsOptions table option.

Display columns like mrt-row-numbers and mrt-row-select don't have column hiding enabled by default, but you can enable it with the displayColumnsOptions table option.
To turn column hiding back on for display columns, you'll need to check out the Display Columns Feature Guide for more information on the displayColumnsOptions table option.

Customization
Customization is key to making your table's columns more user-friendly. You can use the `colspan` attribute to merge two or more columns into one.
To make your columns more interactive, you can add a checkbox to each row using the `input` element. This is shown in the example where a checkbox is added to each row to select or deselect a row.
By adding a checkbox to each row, you can allow users to select multiple rows at once, making it easier to perform bulk actions on the data.

Dynamically Hide
Dynamically Hide columns is a powerful feature that allows you to control how columns are hidden in real-time.

You can use state instead of initialState along with the onColumnVisibilityChange table option to dynamically hide columns.
Alternatively, you can use the setColumnVisibility table instance API to achieve the same result.
This feature was introduced in v2.3.0, giving you even more flexibility to customize your table's layout.
By using one of these methods, you can create a more interactive and user-friendly experience for your users.
Custom Menu
Customizing the menu in Material React Table can be a bit tricky, but it's not impossible. The MRT_ShowHideColumnsMenu component is quite opinionated and not easily customizable, so it's best to build your own new button and menu from scratch using the Table and Column Instance APIs.
You can't customize the menu by overriding it, so it's better to create a new one. This will give you more control over how it looks and behaves.
If you only want to customize the buttons above the columns menu, you can import and use the MRT_ShowHideColumnsMenuItems component, which renders the columns in the list with toggle switches.

Visibility
To control the visibility of table columns, you can use the attribute data-visible. This attribute is a boolean value that determines whether the column is visible or not.
By default, the data-visible attribute is set to true, which means the column is visible. To hide a column, you can set data-visible to false. For example, Column 1 will hide the column.
You can also use the enableHiding option to control column hiding. This option can be set to false to disable column hiding altogether. Alternatively, you can set the enableHiding option to false for specific columns to disable their hiding.
Here are some key options for controlling column visibility:
- enableHiding: a boolean value that determines whether column hiding is enabled
- columnVisibility: an object that specifies the initial state of column visibility
- onColumnVisibilityChange: a function that is called when the column visibility changes
You can also use the setColumnVisibility table instance API to dynamically control column visibility. This API allows you to change the visibility of columns at runtime.

Disable
You can disable column hiding altogether by setting the enableHiding table option to false. This is a simple way to turn off this feature if you don't need it.
To disable hiding specific columns, you can set the enableHiding column option to false per column. This is especially useful if you only want to hide a few columns.
If you want to hide certain columns by default, you can specify column visibility in the initialState.columnVisibility table option.

Visible
The Visible feature is a key part of controlling column visibility in your application. You can set the `data-visible` attribute to `false` to hide a column item.
To hide a column, you need to set the `data-visible` attribute to `false`. This attribute is a boolean value, so you can simply set it to `false` to hide the column.
Here's a quick reference to the `data-visible` attribute:
- Attribute: `data-visible`
- Type: Boolean
- Detail: Set false to hide the column item.
- Default: true
- Example: Column Visible
You can also hide columns by default by setting the `columnVisibility` state or `initialState` to hide the desired columns by id. This allows you to control the visibility of columns even before the user interacts with them.
By default, column hiding is only enabled on data columns. If you want to enable column hiding on display columns as well, you'll need to set the `enableHiding` option to `true` in the `displayColumnsOptions` table option.

Card Visible
The Card Visible attribute is a Boolean value that determines whether a columns item is displayed in the card view state. It's set to true by default.

To hide the columns item, simply set the Card Visible attribute to false. This is a straightforward way to control the visibility of a card's content.
Here's a quick rundown of the Card Visible attribute's properties:
- Attribute: data-card-visible
- Type: Boolean
- Detail: Set false to hide the columns item in the card view state.
- Default: true
- Example: Card Visible
Extensions and Modes
You can toggle the visibility of a column using the columns visibility extension, which allows users to hide or show specific columns.
This feature is useful for customizing the table layout to suit different needs. By assigning a priority to each column, you can define which columns are most important to show across various widths.
To apply the column chooser mode to a table, you'll need to add specific attributes to the table element: data-role="table" and data-mode="columntoggle". An ID attribute is also required to associate it with the column chooser popup menu.
This approach helps users choose which columns they want to see by tapping the "Columns..." button, which opens a dynamically generated list of columns based on the table markup.

Toggle Mode Works

The column toggle mode is a clever feature that automatically hides less important columns at narrower widths and surfaces a button to open a menu that allows the user to choose what columns they want to see.
This mode is achieved by assigning a priority to each column, which helps define which columns are most important to show across various widths. The priority is assigned using the data-priority attribute on the header elements.
The column chooser menu is populated by parsing the values (or abbr title) of the first row of header (TH) elements. Only headers that have a data-priority attribute are included in the column chooser.
The automatic column hiding behavior is accomplished by CSS media queries that hide or show columns based on priority levels at various screen widths. This is done to provide a sensible default for showing the most important columns that will fit on a device.

Here's a breakdown of the media query block that you can copy and customize for each project:
These media queries are used to hide or show columns based on priority levels at various screen widths. The user preferences take precedence over the priority mappings, so if a column is manually checked, it will remain visible across all screen widths until the page is refreshed.
The column chooser menu gives users the ability to override these defaults and choose which columns they want to see.

jQuery Table Row
jQuery Table Row is a powerful tool for managing table data. You can delete a table row with just one click using jQuery, as demonstrated in the article "Using jQuery to Delete a Row in a Table by just Clicking on it".
Deleting a row is just one aspect of table management, and jQuery offers more features. In another article, it's shown that you can hide a table column with just a single line of jQuery code.
