[代码]LVC ALV最多能显示多少列

REUSE_ALV_GRID_DISPLAY_LVC创建的alv能显示很多，很多列，不止255列，具体最多多少列也不太清楚，写了个小程序，如下：

 

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28

REPORT ztest_alv_max_columns.   DATA:lr_ref TYPE REF TO data. DATA:cn(6) TYPE n. DATA:fcat TYPE lvc_t_fcat,      ls_f LIKE LINE OF fcat. FIELD-SYMBOLS:<fs_tab> TYPE table.   DO 9800 TIMES.   cn = sy-index.   CONCATENATE 'C' cn INTO ls_f-fieldname.   ls_f-datatype = 'CHAR'.   ls_f-reptext = cn.   ls_f-intlen = ls_f-outputlen = '15'.   APPEND ls_f TO fcat. ENDDO. CALL METHOD cl_alv_table_create=>create_dynamic_table   EXPORTING     it_fieldcatalog = fcat   IMPORTING     ep_table        = lr_ref. ASSIGN lr_ref->* TO <fs_tab>. CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY_LVC'   EXPORTING     i_callback_program = sy-repid     it_fieldcat_lvc    = fcat   TABLES     t_outtab           = <fs_tab>.

可以看到上面程序显示了9800列之多，相信大多数alv都能满足了。。。
