Whenever data is loaded into a Table, the columns are automatically generated. You can add, remove, or modify columns by accessing the table properties under the column section. You can also rearrange the columns by dragging and dropping them.
Use dynamic column​
The Use dynamic column toggle allows users to dynamically set the columns of the Table using a JSON value.
For example, if you enter the below JSON, the table will display a column labeled "Name" where the data entries are editable strings, restricted in length between 5 and 20 characters, displayed in white text on a black background.
{
"name":"Name",
"columnType":"string",
"key":"first_name",
"cellBackgroundColor":"#000",
"textColor":"#fff",
"isEditable":true,
"regex":"",
"maxLength":20,
"minLength":5,
"customRule":""
}
