Fixed header function

When scrolling data, the header is fixed to facilitate viewing the header information of each column

The fixed header of this component adopts the double header method. When there is a common problem, the column is not aligned. Please add some styles according to your actual situation.
,Please set the width of each column as much as possible to avoid the problem of misalignment of column width

Set Height=200 fixed header

Demo

Example of vertical scroll bar after more data is loaded

Please set a column width, allow a column width not set, auto-fill

Loading...

Set the Height=200 fixed header, when the displayed data on each page is 10 rows, the height exceeds the set value 200, A vertical scroll bar appears on the Table component

Demo

All columns are set to width, and a horizontal scroll bar will automatically appear when the screen is too small

Loading...

Set the AllowResizing property while fixing the header so that the column width can be adjusted

Demo

By setting the Height parameter to fix the header,
, by setting AllowResizing , the parameter allows the column width to be adjusted

Loading...

Do not set the Height value to adapt the height through the parent container

Demo

In this example, the Table table component cannot set the height because the height may not be known. The parent container may get the height through the style. At this time, the Table component will try to Use adaptive fill to fill the height, this application scenario is the most in actual combat, in this example, the simulated parent height is 300px

Seems like the connection with the server has been lost. It can be due to poor or broken network. Please hang on while we're trying to reconnect...
Oh snap! Failed to reconnect with the server. This is typically caused by a longer network outage, or if the server has been taken down. You can try to reconnect, but if that does not work, you need to reload the page.
Oh man! The server rejected the attempt to reconnect. The only option now is to reload the page, but be prepared that it won't work, since this is typically caused by a failure on the server.
