阅读更多关于 How to change background color of an edited cell in JTable?

问题 I searched everywhere but I still can't seem to find an answer to my question. I've read all about cell renderers and cell editors but still no idea... I have a JTable, and I want to make sure that the users clearly see which cell they are editing. by default, the edited cell in JTable gets a darker border, but i would like to make the background green. I can make it green when selected, but as soon as I start entering data, the green background disappears and I'm writing into a white cell.

使用PHPExcel 对表格进行，读取和写入的操作。。。。

阅读更多关于使用PHPExcel 对表格进行，读取和写入的操作。。。。

下面的代码是使用PHPExcel 对多个表格数据进行读取，然后整合的写入新的表格的方法！！！代码有点粗糙，多多保函！！！这里有些地方注意下，如果你的表格数据过大，一定要记得修改php.ini里面的相关配置： file_uploads = on ;是否允许通过HTTP上传文件的开关。默认为ON即是开 upload_tmp_dir ;文件上传至服务器上存储临时文件的地方，如果没指定就会用系统默认的临时文件夹 upload_max_filesize = 8m ;望文生意，即允许上传文件大小的最大值。默认为2M post_max_size = 8m ;指通过表单POST给PHP的所能接收的最大值，包括表单里的所有值。默认为8M 一般地，设置好上述四个参数后，上传<=8M的文件是不成问题，在网络正常的情况下。但如果要上传>8M的大体积文件，只设置上述四项还一定能行的通。进一步配置以下的参数 max_execution_time = 600 ;每个PHP页面运行的最大时间值(秒)，默认30秒 max_input_time = 600 ;每个PHP页面接收数据所需的最大时间，默认60秒 memory_limit = 8m ;每个PHP页面所吃掉的最大内存，默认8M 把上述参数修改后，在网络所允许的正常情况下，就可以上传大体积文件了 max_execution_time = 600
