Swing jtable add text input boxes to table cells

Adding text input boxes to the jtable unit is common. This method is usually used in development to control the input in the table.
Implementation Method:
Rewrite: tablecellrenderer Interface
Component gettablecellrenderercomponent (jtable table,
Object value,
Boolean isselected,
Boolean hasfocus,
Int row,
Int column) returns the component used to draw cells. This method is used to configure the Renderer properly before painting.

Parameters:
Table-The jtable to be drawn by the Renderer; it can be null.
Value-the value of the cell to be rendered. This value is interpreted and drawn by the specific Renderer. For example, if the value is a string "true", it can be rendered as a string or as a selected check box. Null is a valid value.

Isselected-if you use the highlighted display of the selected style to present the cell, the value is true; otherwise, the value is false.
Hasfocus-if it is true, the cell is properly rendered. For example, place a special border on a cell. If you can edit the cell, it is displayed in color to indicate that the cell is being edited.
Row-row index of the cell to be drawn. When the header is drawn, the row value is-1
Column-column index of the cell to be drawn
