包路径：ij.measure.ResultsTable
类名称：ResultsTable
方法名：getLastColumn

ResultsTable.getLastColumn介绍

[英]Returns the index of the last used column, or -1 if no columns are used.
[中]返回上次使用的列的索引，如果未使用任何列，则返回-1。

代码示例

@Override
public int getColumnCount() {
  // NB: Last column gives the index of the last column in use, but there may
  // be columns before that index which are null. Additionally, cannot use
  // getHeadings().length or getColumnHeadings() because if there is a row
  // label that will also be included in the returned structures
  int count = 0;
  for (int i = 0; i <= table.getLastColumn(); i++)
    if (table.columnExists(i)) count++;
  return count;
}

  // to "---"
