enable dynamic table column width

Going over the docs, there does not seem to be a way to to resize a table column's width once drawn.
Seems like the only way to ensure all data is visible would be auditing the data going into tables to predefine a minimal width for each column so as to not cut-off any data, and would seem wasteful when the total available width can change depending on display - Best to let viewers control their table layout as fits their display.

首先阅读链接的 JavaScript 表格文档，并找到表格的实现及其现有测试；issue 未指定文件或测试入口。定义支持的列调整大小行为，并验证查看者可以调整列宽，而不会因显示宽度变化而导致数据被截断。
